Hi there! I hate to start a new topic for every question, but I guess that is the custom on Group DIY.
Is triode matching critical for the V2 stage? I have access to a few very fine used 6DJ8-type tubes and I'm not sure what my selection criteria should be. I've read somewhere that the two triodes work in "parallel"--which seems to suggest that both triodes are single ended. Does that mean that matching is critical or not critical? If both triodes are single-ended, parallel, class-A, I assume that they shouldn't need to be perfectly matched. Am I way off-base here?
I know that this question involves a bit of theory that is beyond my current level of understanding--I'm still trying to learn some basics about tube amp typologies and I'd love a bit of guidance.
As a broader question, and for my general education, what amplifier typologies necessitate closely matched gain stages? Am I correct in surmising that this is usually only needed for push-pull configured stages?
