[QUOTE="Ampdog, post: 46119, member: 144"] I said in previous post Forget that, D - we will not disturb Ludo's peace. I looked up several Marshalls' schematics, guessing that they would probably not have changed a 'good' power amp schematic. They did not. All seem to have fixed bias for pentode connected EL34s, fed by an ECC83 ltp phase inverter. No NFB, no UL. No output transformer sectionalising. You could include rewinding that in your adventurousness, but I do not imagine you want to be that pioneering. Are you looking for a complete amp just to tweak, or are you thinking of building one from scratch given all the information? [/QUOTE]
