Hello, everyone,
For years now I have been casually gathering schematics and information regarding a v76m channel strip that I wish to build by next year. One of the things that I have asked about in the past is what would be the affect on the circuit regarding audio if dropping resistors were used instead of the two inductors? I also recently noticed that both of the EF804s's use dropping resistors directly from the B+ supply so what was the reason to use inductors instead of resistors for the E83F and EF804? I realize that this was designed in an era where component sizes were much larger than ones with the same values as today and the tolerances were greater so maybe that had something to do with it. Another question is couldn't the primary winding of the output transformer be used to supply B+ to the E83F as it is done with tube guitar amps and even 1073/1290 style circuits?
I should clarify that I am not trying to build something that is exactly the same as an original v76m as I feel such pursuits are in the end not worth the time or money to gain that extra 0.1-1% "better" sound. The v76m is know for sounding big and awesome. I am using this circuit as a foundation to create something that is also big and awesome. And equally as important, something very quiet.
Thanks!
Paul
