[QUOTE="Ampdog, post: 54022, member: 144"] I just had a rave report back from the owner about the 'superiority' of the converted model compared to the original. (I do hope I will not now be engulfed by other owners - apparently this man knows others with similar possessions.) Apart from lowering the heater voltage, I simply changed the parallelled input triodes (12AU7) to triode amplifier - concertina splitter, and added 20dB of NFB (quite allied to the Williamson). I think the main change in sound was probably due to the now DF of some 30 compared to the original DF of about 1,8. Anyway, I think it is a 'chassis' with possibilities, owing to the very good OPT as stated before. No idea of what they cost locally. [/QUOTE]
