Brian May’s Legendary Deacy Amp and its background:
Good examples of Brian May’s use of the Deacy Amp for recording can be found in the following YouTube videos:
The second video shows a rare ‘live in the studio’ recording done at VH-1 studios in London during July 1998. Several songs were recorded by Brian and his band at VH-1 shortly before a world tour to promote the album ‘Another World’. In this clip Brian plays my Red Special replica ‘Paul’ through the original Deacy Amp, and right from the first seconds you will hear the Deacy Amp’s unique tones:
Lots of Deacy Amp rich guitar harmonies can be heard right from the opening seconds of Dreamers Ball. The Deacy Amp is used by Brian all through this fabulous song from Queen’s “Jazz” album, with his Vox AC30 occasionally added for contrast such as during the main guitar solo section:
My phone call interview with ‘Queen’ bass player John Deacon in July 1998:
John was a very nice fellow to talk to and gave his account about finding the Deacy Amp circuit board and then what happened with putting the amp together and using it as a practice amp, and then taking the amp to band practice with Freddie, Brian and Roger.
By the way, John Deacon did not tell me that he changed the Deacy Amp’s front end – this came from something that Brian had told me during 1998 at Allerton Hill when we began pulling apart and examining the Deacy Amp. Brian said that he thought they had changed something in the amp to help it cope better with the signal coming in from the treble booster. We do not know whether this happened or not, and when I asked Brian again about this in 2007 he laughed and told me that he couldn’t remember. In the piece I wrote for Brian’s website www.brianmay.com about the Deacy Amp, I included this information based on what Brian had previously said, but I suspect now that nothing may have been changed in the front end input stage.
In the phone call with John I asked him if he had ever made Brian a treble booster in those early days of Queen, because for many years it has been reported that he had. John told me that he had not made a treble booster for Brian.
From my notes on the phone call with John Deacon 22nd July 1998:
John said that he found the amplifier section in the back of a skip which was sitting on the side of the street in London, and that he noticed the wires dangling over the edge of the skip and picked it up before it was thrown out. John said that he was studying for a degree in Electronics at the time and was always tinkering with electronic bits and pieces, and that the circuit board looked interesting to him when he first saw it. He thought that the transistor amplifier might have come from a cassette player or a radio. John thought at the time that he might possibly use it as a small practice amplifier – he played guitar as well as bass. John thought that this had happened in about 1972 and that he was already playing with Brian at this time.
John said he already owned the hi-fi bookshelf speaker box which he then modified so that it housed the amplifier circuit board inside with no controls at all on the outside of the box. John liked the simplicity of only having a jack socket to plug into with the amp’s volume set internally at full, although he said that initially he probably had a volume control hanging on the outside somewhere. The amp had a warm and pleasant sound although John said that it was always partly distorted and would never sound clean.
John told me that through some chance he showed the amp one day to Brian when he brought the amp along to band practice, and said Brian was immediately interested in the amp’s possibilities especially when he used his Red Special guitar and treble booster with it. John said that with the Red Special and treble booster, the little amp offered a pleasant pretty type of saturated distortion which was utterly unique and very different to the ‘cutting harder sawtooth transistor distortion’ found in many effect pedals and amps of the time.
John remembered that the sound engineers who they worked with liked the way the little amp behaved in the recording studio where it would produce a ‘consistent response’ as he termed it, whereas the engineers found it more difficult to capture on tape the excitement and dynamic live sound of Brian’s Vox AC30 amps. However John quickly mentioned that all the work and discussions with sound engineers was never his area of interest, and therefore he was never privy to detailed information in this area.
When I asked John about whether he had made a treble booster for Brian at this time in the early/mid 1970s, he told me that he had not.
Origins of the Deacy Amp circuit:
In 2013 Dave Doughty, Mitch and the other folks at http://www.antiqueradios.com finally revealed that the Deacy Amp pcb is from a Supersonic PR80 portable radio.
Interestingly, John Deacon had originally told me in 1998 that the circuit might be from ‘ a cassette player or radio’ so it looks like his intuition was very accurate.
In 2014 Manuel Angelini from France located an original Supersonic PR80 circuit board which appeared to be identical to that of Brian May’s Deacy Amp. Manuel has now become the world expert on the Supersonic PR80 and has done extensive research on the Supersonic factory and the Supersonic PR80 origins.

Manuel’s Youtube video ‘A Supersonic Story’ shows some of the Supersonic PR80 radio’s origins with suitably theatrical over the top music:
Designer of the Deacy Amp circuit: Nigel “Bob” Goodridge
This article was written by Nigel’s son Peter Goodridge on 3rd June 2020 and has been very kindly provided for publication:
“I was not aware of the mystery of the Deacy Amp and the Supersonic PR80 radio until I was on Facebook and someone had posted a picture of the old Supersonic Radio Factory in Bulawayo in what was then Rhodesia. I responded and posted that my late Dad, Nigel “Bob” Goodridge was the Chief Design Engineer at Supersonic from 1961 until the late 1970’s and was responsible for the design of a large number of portable radios, car radios and stereo hi-fis during that time.
Nigel Goodridge, better known to his friends as “Bob” Goodridge as he didn’t like the name Nigel was a Radio Officer in the Royal Navy during the Second World War and became an Engineering Apprentice with PYE Radio in the UK after he was de-mobbed from the Navy.
During the early 1960’s he was headhunted in London by Jacques Chassay who was the founder together with his brother of Supersonic Radio in Bulawayo, Rhodesia in the 1950’s. My Dad took the whole family from the UK to Rhodesia in 1961 and commenced his role as Chief Design Engineer at the Supersonic Radio Laboratory in Bulawayo.
During this time he was responsible for the design and development of a large number of portable radios, including the PR80 which were designed specifically for the local market in Rhodesia and South Africa.
I can remember as a young boy and a teenager growing up in our home in Bulawayo always surrounded by music, radios and hi-fi sets and how excited my Dad would be when he brought home one of his designs for us all to test drive. He was a very modest man and went about his work with immense enthusiasm and passion.
He left Supersonic when he and my Mum, Joan Goodridge decided to move to Johannesburg in South Africa in the late 1970’s. He remained very involved with the radio industry and was a Consultant to a number of Companies in Johannesburg.
Nigel “Bob” Goodridge passed away in April 1992 in Johannesburg after being diagnosed with a brain tumour in November 1991. I only wish that he could have had some idea how his design of the PR 80 would have had such an impact on the music of Queen.”

Following on from Peter Goodridge’s article above, I asked Peter if he would mind writing for us a slightly more detailed biographical piece about his father Bob. Given that Bob is now being recognised by the guitar world as the designer of Brian May’s famous Deacy Amp circuit, I felt it worthwhile for people to be able understand more about the person that Nigel “Bob” Goodridge was, and comprehend the circumstances which shaped his life and then took him and his family from London to a life far away in Rhodesia in the early 1960s when Bob accepted Jacques Chassay’s offer of being Chief Design Engineer at Supersonic Radio Laboratory at Bulawayo.
Peter has very kindly written this article and provided some photos of his dad Bob:
Nigel ‘Bob’ Goodridge – Electronics Designer – Biography by Peter Goodridge
“Nigel Robert Goodridge was born on 4th May 1924 in Weymouth England. He was an only child although he had two much older step-brothers from his Mother’s first marriage.
Bob joined the Royal Navy at a very young age as a Cadet Officer and then World War II broke out. He attained the Rank of Sub Lieutenant and spent a lot of time in the North Atlantic as a radio officer protecting convoys and then later in the Middle East. Bob has an “oak leaf” on one of his medals which means he was mentioned in despatches for some acts of bravery, but he later never spoke about it.
He got the name Bob in the war because he thought Nigel wasn’t a very masculine name so he told everyone he was Robert Goodridge, using his middle name instead, and they started calling him Bob. Later everyone in Bulawayo Rhodesia knew my Dad as Bob Goodridge.
Bob met his future wife Joan at the end of the war and they married in 1947. Bob was still in the Navy at that time but Joan was not happy about him being away so much, so he decided to leave and study electronics at the University College Southampton.
My Dad then joined PYE Radio in the UK as an apprentice. Fast forward to 1961 when we were living in the UK just outside London, when Bob came home and said we were all going to live in Africa in Southern Rhodesia as it was known then. He had been recruited by Jacques Chassay (the original owner along with his brother Arthur of Supersonic Radio) who had been in the UK recruiting for skilled employees.
Bob left for Rhodesia first and then the rest of the family joined him three months later….my Mum, my older sister Carole and myself. We moved to Bulawayo and by then my Dad was well established in his role as Chief Design Engineer at Supersonic.
Bob was responsible for designing a large number of portable radios, car radios and stereo hi-fi systems, and amongst them was the PR 80 (Portable Transistor Radio FM/AM).
My Dad had some health issues in the early 1970s due to angina (hardening and narrowing of the arteries of the heart), and his doctor told him that if he didn’t stop smoking and lose some weight he was going to die a young man. Dad got a fright and stopped smoking very soon thereafter and then started jogging around the block to lose some weight.
The jogging became an absolute obsession with my Dad, and he eventually became one of the top long distance runners in his age category in the country. He ran a great many marathons and half marathons. By the time of the mid-late 1970s the Rhodesian War years were upon us and I had left school and joined the Police in CID and then I was seconded into Special Branch.
My Dad was still at Supersonic but by the end of the 1970s he and Mum decided that Rhodesia was not going in the right direction so they left for Johannesburg South Africa where I was already living, having left Rhodesia in 1978. My sister Carole had earlier gone back to the UK to live in Wales, where she still lives today.
Dad then worked for an electronics company in Johannesburg on a consultancy basis, although I can’t remember their name. He travelled regularly to Japan on business and it was on one of these trips in 1991 that he collapsed. In November 1991 the doctors in Johannesburg diagnosed an aggressive brain tumour and gave him three months to live.
It is the only time I had ever really lied to my Dad as I went to the hospital with him and the Doctor took me aside and told me it was three months. My Dad knew he was sick and when I walked back into the room he just said “how long have I got?” I told him 6 months. I just couldn’t tell him three, it sounded too short.
Bob passed away on 15th April 1992, nearly exactly three months after his diagnosis. Dad was my best friend and I miss him greatly still.
I hope this gives you some insight into the remarkable man who was Nigel “Bob” Goodridge.”

Manuel Angelini has kindly provided an article and photos for publication which describes the background of the Supersonic company and the key people who were responsible for the development of the Supersonic PR80 radio
“Supersonic PR80 – the men behind the radio by Manuel Angelini:
It all started in 2013, when the good guys at antiqueradios.com identified the Deacy audio amp board as coming from a Supersonic radio, manufactured in Southern Rhodesia in the mid-1960s. That was a real breakthrough, as no-one before them ever had a precise idea about the Deacy origins.
Supersonic has quite a unique story. Created at the beginning of the 1950s by two brothers, Jacques and Arthur Chassay, who were of Canadian origins, it became one of the main manufacturers of radios in Africa, selling its radios, radiograms, gramophones… worldwide by the end of the decade. Most of the parts they used for their radios were designed and manufactured in-house.
This was possible because they had chosen to have a strong designing team. In those days, Supersonic had about 5 electrical and 5 engineering designers from a total laboratory compliment of around 12 people. An electrical and mechanical person worked together on each product. The electrical engineer was responsible for the circuitry, schematic, layouts and component details, and the mechanical engineer did all the drawings, chassis and cabinet designs.
By the end of 2013, I have been in touch with many former Supersonic employees, many of them remembering fondly of their time in the company. We talked about the people they were remembering of, and two names were often coming up : Bob Goodridge and Dave Sharpe, who were working in the development lab in the 1960s. They knew Bob Goodridge had sadly passed away at the beginning of the 1990s, but no-one knew where Dave Sharpe was living. I was lucky to get in touch with someone who knew him, because they were running together in their Rhodesian days, and I managed to get in touch with Dave Sharpe. Dave confirmed that Bob Goodridge and himself designed the Supersonic P.R.80, the radio that was to give birth to the Deacy amp, used by Brian May in many Queen songs. This was a fantastic surprise for him, and he was happy to tell me much more about Supersonic and its history.
Fast forward 7 years. As I own many pictures of the Supersonic people and premises in the 1960s, I posted one of them on Facebook, on a Rhodesian page. I had many posts and “likes” from people having worked there across the years. But one person also posted about his Dad : Peter Goodridge, son of Bob Goodridge. We then exchanged many e-mails about his Dad, and his design work for Supersonic. The Deacy/Supersonic P.R.80 story was such a surprise for him, but also brought back so many personal memories… because of its tone and history, the Deacy is really a unique amp !”

History of the Greg Fryer/Nigel Knight Deacy Amp replica 1998-2011:
Below is an article in red text that I wrote in 2011 for inclusion in the KAT produced Brian May Deacy Amp, and since then I have edited some parts for more thoroughness and detail. I intend to post more detail and photos soon about the early years of the Deacy Amp replicas and research. Cheers, Greg Fryer 3rd June 2020
The Deacy Amp project was began by myself during the work I did in 1998 for Brian May at his London Allerton Hill studio. Brian gave his encouragement to me opening up the Deacy Amp and investigating its unique circuitry and speakers. Technical assistance came from David Petersen who I initially contacted in early 1998 on behalf of Brian’s studio to help with Brian’s Vox AC30 amp repairs and upgrading. After I then received the OK from Brian to investigate making 3 replicas of the Deacy Amp I asked David if he could assist me with replicating the germanium transistor/transformer coupled amp circuit of the Deacy.
One thing led to another as the ‘Deacy Amp momentum’ grew and in July 1998 I had the wonderful opportunity of interviewing Queen bass player John Deacon regarding the origins of the Deacy Amp.
When I returned home to Sydney Australia in late August 1998, I brought back one of our Deacy Amp replicas, and set about continuing the Deacy R&D process with Colin Bloxsom who was a Sydney luthier and guitar electronics expert. Our best sounding prototype Deacy replica was what I call the Mk II, and to my ears this is still the best sounding Deacy Amp that I have heard apart from Brian’s original Deacy Amp itself.
Photos of Deacy Amp replica Mk II courtesy of Kees Van Ede:
In 2003 I asked Nigel Knight to assist me with technical expertise in the Deacy Amp project, and over several years we developed further prototypes which I then showed to Brian May on 2 trips to the UK in 2005 and 2007.
In early 2008 Nigel asked to take over the R&D task completely. The prototypes that we had developed during 2003-2008 were good sounding but disappointingly were not an improvement soundwise on my 2003 Mk II Deacy and we were at a frustrating point with the amp’s development. We were obviously hoping to make the Deacy Amp for commercial sale at a later date as part of the ‘Brian May/Fryer’ product range but there were still some obstacles to overcome technically. Against my better judgment, I agreed to let Nigel Knight take over complete control of the Deacy Amp project. Nigel then met with Brian and Pete and decided to start again with a clean sheet and this meant that he re-examined the original Deacy amp to a higher degree than we had before. Previously we had been very reluctant to take apart several fragile areas because of the danger to this irreplaceable amp.
Since January 2008 there has been a great effort from Nigel Knight in order to get this innocuous looking little amplifier produced and brought into being. Almost everything in this replica amplifier has had to be custom made specially for it and this has needed great amounts of time and expense devoted to the project.
Several people involved in the project have contributed articles to the Deacy Amp booklet – this part below in red is from my article:
Background of the Legendary Deacy Amp and the development of the replica by Greg Fryer:
In July 1998 John Deacon related to me the circumstances surrounding his putting together of this unique sounding amplifier and speaker cabinet.
John literally found the circuit board as he was walking down the street one day in London – this occurred in early-mid 1972 when he was first playing in “Queen” with Freddie Mercury, Roger Taylor and Brian May. Being a keen electronics experimenter (John was then studying for an electronics degree), his attention was drawn to the wires that were dangling over the side of a builder’s skip which was filled with rubbish and about to be taken away to the tip.
These wires were attached to a circuit board and John’s curiosity led him to examine the board to see if he could salvage it and put it to some use. He initially thought that the circuit board might have come from a battery operated cassette player or radio, and after inspecting it further decided it would do the job as a small practice amplifier for guitar (John played guitar as well as bass).
John coupled the newly found circuit board with a spare bookshelf speaker cabinet which he had lying around – the circuit board was fixed inside with two screws and the finished product featured no controls whatsoever. On the back panel of the cabinet was fitted a single jack socket to plug the guitar lead into – the amp’s power was turned on by simply connecting the two battery clips which came out from the back panel to a large 9 Volt PP9 battery.
With a standard guitar plugged in, John said the amp possessed a warm and pleasant if partly distorted sound, but lacked brilliance or much definition. However a new way of using this little amp was about to be found that would change its sound and make it an invaluable part of Queen’s recording armoury.
On one occasion John brought his practice amplifier along to band rehearsal and showed it to Brian. Immediately Brian was interested in the amp’s possibilities once he heard how it behaved when he plugged in his innovative home made Red Special guitar and his single transistor treble booster pedal. Using the guitar and treble booster together changed the amp’s sound dramatically, overdriving both the input and output stages and producing a richly distorted yet defined and sustained sound which resembled such things as violins, cellos and even vocals.
John commented that the rich saturated compressed type of distortion produced by the combination of Red Special guitar, treble booster and Deacy Amp was very unique and was different to the harder sounding distortion common at the time in many guitar effects and amps. He mentioned that the recording engineers that the band were working with particularly liked the way the little amp behaved in the studio. Here the amp would produce a consistent response John said, whereas the engineers found it more difficult to capture on tape the exciting and dynamic sound of Brian’s Vox AC30 amps.
John’s small amplifier became known as the “Deacy Amp” and featured regularly on Queen albums where Brian used it for his creative, highly original multi-tracked guitar orchestrations. These were painstakingly built up line by line (and even note by note on some of the more complex pieces such as “Good Company” from Night At The Opera). Although the Deacy Amp is a deceptively simple looking piece of equipment, the wide number of creative sounds that Brian has managed to coax from it over the years belies the outwardly simple appearance.
Brian has described the way that the Deacy Amp’s sounds sit and blend together when recorded as being “symphonic”, whereas when the AC30 was tried for the layered sounds it didn’t have the same character and effect in the way the notes blended together. The tracks “Procession” and “The Fairy Feller’s Master Stroke” from the 1974 album “Queen II” saw the first recorded examples on a Queen album of the Deacy amp.
Perhaps the best known example of the amp’s use is on “God Save The Queen” from 1975’s “A Night At The Opera”, whilst possibly the most unusual use was for all of the jazz band sounds on the song “Good Company” (trombones, clarinets and all!) from “A Night At The Opera”.
The Legendary Deacy Amp continues to this day in good health and continues to occupy an important place in Brian May’s recording studio.
Making of the Deacy Amp replica:
During the early months of 1998 as Brian May was completing the recording of the “Another World” album at his London Allerton Hill studio; Brian, Pete Malandrone and I discussed the idea of making a replica of his Deacy Amp. For some time Brian and Pete had been aware of the need to have a good quality replica as a backup for Brian’s own use in case anything ever went wrong with his original amp. Due to the great interest shown over the years in the Deacy amp we also thought it was worthwhile to start the process of examining the original amp so that we could possibly one day offer replica amps for sale.
At that point we had little idea of the amount of work that might be involved, how long it might take and how much it might cost, or who we might have to find as partners to be able to bring the project into physical reality and have amps eventually manufactured. As the project began I asked assistance initially from two friends in London and Sydney who were experienced guitar and amp repairers: Dave Petersen and Colin Bloxsom.
In July 1998 Dave Petersen and I built 3 replica amps which were assembled in Brian’s Allerton Hill studio, and after I returned home to Australia in late 1998 Colin Bloxsom worked with me on further development of the Deacy amp design. When Colin left to go overseas I then asked Nigel Knight if he would like to be involved in the Deacy development project.
I would personally like to thank these three gentlemen for their invaluable technical assistance, and in particular Nigel Knight. Without Nigel’s specialist electronic expertise and dogged determination to see the job through to the finish, the Deacy Amp replica would not have come about. I would also like to thank very much Brian May and Pete Malandrone who have always been very encouraging during the development of various Deacy Amp prototypes and have always been extremely generous with both access to the original amp and with their time during the years of development.
The first 3 replica amps that Dave and I built during July/August 1998 took a fair bit of guesswork regarding the driver and output stages. Plotting out the basic circuit was fairly straightforward but there were areas that kept on being an intriguing mystery until Brian finally gave the go-ahead to take everything apart in January 2008. Because of the fragile and delicate nature of these areas of the original amp (mainly the transformers and some circuitry immediately adjacent to the transformers), we were extremely reluctant to take the amp completely apart due to the risk of doing irrepairable damage. Dave assured us that the Deacy’s transformers were none that he had seen before and were not available commercially. Brian and Pete didn’t want to wind up with a non functioning Deacy Amp and I certainly didn’t want to be remembered as the man who killed the Deacy Amp! So we agreed to take educated guesses for the transformers (based at first on the old Mullard reference manual and advice from transformer manufacturers), and pinned our hopes that through trial and error we would eventually get the sound correct. There were some surprises and frustrations in store for us….
The speakers were also a critical part of the Deacy sound, and I tested many speakers for these first 3 amps in 1998. Fortunately we managed to find a very good sounding twin cone English made Eurotec 6.5″ speaker, and it was by far the closest sounding to the original Deacy amp’s English made Elac twin cone speaker. These 3 Mk I replica amps sounded surprisingly good in their own right although it was clear to us that there was still much work to do to achieve an identical sounding replica Deacy amp.
Back in Australia in late 1998, I continued the development work with Colin Bloxsom in Sydney and we asked specialist transformer companies to make new experimental coupling and output transformers which were to be wound to different specifications and in various lamination sizes and styles. We also experimented with several circuit variations. Throughout 1999-2001 we made the Mk II version of the amp which sounded closer again to Brian’s original Deacy and its elusive tonal and distortion characteristics.
In 2003 I asked Nigel Knight if he would like to become involved with the Deacy replica project, and he brought to the table his specialist knowledge of “Deacy era” 1950s-1970s transistor and valve electronics as well as his keen interest in Brian’s Red Special guitar. Over the next 4-5 years several prototype amps were built and modified whenever spare time was available, and we both had a lot of fun producing new versions of the amp and trying to crack the Deacy’s tonal mysteries. During this time we continued to refine the transformer specifications, trial new speakers and refine the overall circuit. In both 2005 and 2007 I visited London with prototype amps to show Brian and Pete (amongst other things like Red Special and AC30 stuff), and to make further examinations scope tests and A/B test recordings of the original Deacy amp. In the 2003-2007 amps we sometimes used a Phillipine made Dai Ichi twin cone speaker which was strong in some sonic areas that the Eurotec wasn’t. By 2007 Nigel and I had gone about as far as we could go based on our still incomplete knowledge of the Deacy’s transformers and circuit, and we were also in need of a speaker that would sound identical to the tonality, focus and volume of the original Elac. As good as our previous Eurotec and Dai Ichi speakers had been, they were just not the same as the old Elac so it was clear that we would have to take the extra step of finding a speaker company that was capable of producing a custom made replica of the Elac 6.5″ twin cone speaker, and who was also willing to commit the considerable R&D time towards achieving this.
In January 2008 Brian, Pete and Nigel got together to discuss the Deacy Amp prototype’s future, and to our great delight Brian decided that it was now time to take apart whatever needed to be taken apart from the original Deacy in order to be able to produce an identical sounding amp. Nigel then took on the task of conducting this vital final research work and also began the process of looking for suitable speaker manufacturers who could duplicate the Elac speaker, plus a host of other things.
To be able to produce a replica amp many issues needed to be solved including having custom made grillecloth screenprinted to the exact pattern of the faded original Deacy grillecloth, having custom mahogany veneered chipboard manufactured so that we could then manufacture speaker cabinets that were comprised of the same materials as the original amp, having our stocks of germanium transistors put through an involved and expensive process to make them RoHS compliant, plus a list of other things. Not the least issue to solve was the arduous development of the speaker, and fortunately due to Brian’s long association with Celestion they very kindly agreed to come on board and develop a special replica speaker for our amp. During the 2 1/2 year development process Celestion produced for us over 40 different specification prototype speakers, an astonishing display of their total commitment to the task. Without the development of this Celestion speaker, the final Deacy replica amp would not have sounded correct in all its tonality and detail, so we therefore owe a great deal of thanks to our esteemed partner in this project Celestion!
Well its been a long and often amazing journey, and there have been many times when we have wondered if we would ever see the finishing line. From the very first times I heard the Deacy Amp on the “Queen II” and “Sheer Heart Attack” albums, to me it sounded like an inspired piece of equipment which produced inspired music, nothing like I’d ever heard before and almost “other worldly” and magical in its unique tones and the wonderful passages produced. I am still inspired when I hear those and later Deacy Amp pieces and I sincerely hope that our Deacy Amp replica will be enjoyed by a great many people and will help those people in making their own inspired music.
