Having bought The Beast (STA100) from Tom and established that I am very happy with its performance paired with my Tannoys I am now putting my Radford STA15 up for sale.
Bought on eBay last summer, it was unmolested apart from the replacement of a main power supply capacitor about 30 years ago. The amp has been given a major restoration with a comprehensive recap, upgraded coupling capacitors to Mundorf ZN Film/Foil type, replacement silver plated Audio Note speaker binding posts, new stainless steel valve runners with sockets supplied by Radford Revival and the output impedance selector switches replaced with variable input potentiometers. Thus the output impedance is fixed at 8 ohms at present but this can be easily changed by a technician to 16 or 4 ohms as required. The casework is in good original condition for its age as shown in the pictures.
I can supply the amp with a choice of EL34 output valves: new generic Chinese, lightly used Svetlana SED S Logo originals from St. Petersburg factory, nearly new Tesla originals or nearly new Mullard xf2 Blackburn 'OO' getter with welded plates. I also have several pairs of signal and splitter valves available if required.
The amp owes me £1600 plus valves, so that is what I want for it with the Chinese valves. The SEDs would be an additional £100, the Teslas £200 and the Mullards £750. I know, desirable valves have become ridiculously expensive but I am asking for only half to two thirds of what was paid for them a few months ago.
While the STA100 gives even better control this amp drives my 15" Tannoy Monitor Reds and Monitor Golds with ease and is a joy to listen to. Contrary to opinion some hold it is responsive to changes in signal and particularly power valves. The recapping and other work was carried out by David Coe at ADAudio and most of the pictures below were taken by him during the restoration work.
Collection only from Lymington, Hampshire or meet up somewhere within an hours drive from there.
