Radford Electronics was set up in Bristol by Arthur Radford back in 1959. In some ways Radford was a late starter in the world of high fi delity, especially compared to Peter Walker of Quad or Harold Leak, and the electronics refl ect this. Indeed, Radford’s designs are often described as being the most ‘modern’ of vintage amplifiers.
It was the Series Two amplifiers, soon changed to Series Three, that put Radford’s designs on the map, the Series 3 range comprising two monoblocks – the MA 15 and MA 25 – plus two stereo versions, the STA 15 and STA 25.
In 1955 Wireless World published articles by Quad’s Peter Walker on the practical and theoretical aspects of making a full range electrostatic speaker. That year, he demonstrated two different prototypes developing one for the first public demonstration at the 1956 Audio Fair. Due credit must be given to Walker for the huge amount of pioneering work involved and the brave decision to make it a commercial product.
When first introduced, a single ESL would have set you back £52, yet demand was far greater than supply.
