Since 2008, DoxyWorld has been manufacturing 1W-style transistor recording amplifiers. Our goal is to replicate our model, a small amp based on the Supersonic PR80 radio audio amp section, in tone and in look.
Our products are designed to sound as close as possible to their model. Each product differs on the accuracy of its tone, of its look and the presence of some additional features.
Our products are manufactured by hand in France. When impossible to source, some electronics parts are also hand-made to exact specifications of their vintage counterpart.
Most of our customers use our products with a Red Special guitar and a treble booster. While the treble booster is a 'must-use', our amps will give good results with different type of guitars.
For over 40 years, the true origins of this amplifier were a bit of a mystery... was it coming from a radio, a record player, a baby monitor... ? No-one knew, until 2013, when Dave Doughty, Mitch and the other members at https://www.antiqueradios.com finally revealed that Brian May's recording amp electronics was coming from a Supersonic PR80 portable radio, manufactured in 1964 in Southern Rhodesia (now Zimbabwe).
Having an interest in Queen since the 1970s, and especially in Brian May's recording amp, this radio was a 'must-have'... but none of them was to be found on the usual online auctions websites. So I started a long and difficult quest, mainly in Zimbabwe and South Africa, contacting former 1960s Supersonic employees to know some more about the Supersonic company and the products they then manufactured. Most of these radios have disappeared nowadays, though many had been produced back in the days. I was lucky enough to get in touch with the 1950s and 1960s Supersonic R&D manager, but also with the employee who wound all the audio transformers prototypes for Supersonic at the time. They very kindly gave me some priceless technical informations about the Supersonic range in general, and specifically about the Supersonic PR80 radio. Eventually, my contacts in South Africa helped me finding the original radio, some spare parts, and bought them on my behalf. Thanks to them, DoxyWorld now owns the original Supersonic audio amp board, but also some spare Supersonic audio transformers, one of the keys to the elusive tone of the original amplifier.
Having also access to the original Elac woofer and tweeter, and to the original cabinet, I decided to replicate the amplifier in its finest details. This work took me several years, doing some R&D on every single part of the amplifier and replicating them as faithfully as possible. Having full access to the separate elements that make the amplifier was the key to making our latest replica, the Supersonic Pro, as good as possible, both aesthetically and technically.
