Tomorrow I will try a test from the opposite perspective, which is to just test the isolated performed of the output stage…. I’ll connect a balanced audio output from an interface to some caps and then to the grid inputs of the EL84’s. I’ll leave the grid stoppers in place too, which are at 82k right now.
Will this work ok with impedance relationships? The audio source would probably only have like 50ohms, but those grid stoppers add 82k. Is there some impedance interaction with previous stage that the EL84’s depend on to function?
Maybe I can successfully get the output to perform as it should, and if it does and the audio sounds as one would expect, then I think further reinforces the idea that the preamp and PI sections are being distorted simply because they’re losing their rails quite dramatically.
