an ecc83 would need the wireing to the valve base changing also components changing i am thinking it may be easyer to swap on of the preamp valves also ecc807 and modifie the the preamp to use ecc83 but i would still like to hear from anyone who has tried this or any other solutions

ps the owner has just ordered an ecc807 nos the amp will still need other work one of the caps in the voltage doubling power suppy has a bulge and the anode load resistor in the phase splitter in the working channel is very high in value

if its made by hand it can be repaired by hand
