Radford MA15 power amplifier

The image features a pair of Radford MA15 monoblock valve amplifiers, iconic pieces of British high-fidelity audio engineering from the 1960s. These amplifiers were designed by Arthur Hedley Radford and are renowned for their exceptionally low distortion and high-quality output transformers, which were manufactured in-house. The MA15 is the monophonic counterpart to the famous STA15 stereo amplifier, typically utilizing a pair of EL34 output valves.

Originally founded in Bristol in 1946, Radford Electronics became a benchmark for audio quality, often used in professional settings and by the BBC. Following Arthur Radford's retirement in 1989, the brand's lineage was carried on by Woodside Electronics, founded by John Widgery, a former Radford apprentice. Today, the legacy of the brand continues through Radford Revival, a UK-based craft business that produces faithful recreations and provides restoration services for these classic designs based on original blueprints and handmade specifications. Consequently, the ultimate ownership of the 'Radford' brand name for modern production rests with Radford Revival in the United Kingdom.
