HOWEVER. I know my super basic tube tech. and anyone who knows tubes knows the fairchild twins.
specifically its 20 some tubes and 14(?) or so transformers that act as multiple gain stages, minimizing overall distortion and allowing incredible control over distortion characteristics. never-mind that negative feedback and/or pentodes and all that can sometimes yield even cold sounding amps, while vintage Japanese single triode (300b) theater amps are crazy lush... thats a single, tiny, power tube per channel..... its tricky...
