The Radford sta 15 is arguably the sweetest sounding of all the Radford amplifiers. Add to this auto biasing, and it is an easy amp to own. Readily available and economical EL34 valves make it a cheap amp to own. This amp was owned by a BBC engineer and then left unused for many years.
It has now been sympathetically restored and refurbished. All components have been measured and checked against the original specification. The main dropper and anode load resistors have been replaced with Kiwame resistors. All electrolytics have been replaced with F and T capacitors except for the cathode bypass capacitors which have been replaced with Elna Silmics.
The chrome valve runners have been replaced along with all valve and input sockets. The amp has been rewired as necessary.
The amp produces 25 watts per channel and like most Radfords will drive a wide range of speakers. Output impedance is switchable: 4, 8 or 16 ohms. The amp has been finished with a pair of Audio Note silver plated speaker binding posts.
Audition possible. The amp is located in Wimbledon.
£1,550
