hi!
i am trying to find a good termination and grounding for a transfomer that sees an unbalanced source of about 500R. ratio is 1:2 and the sec acts as a centertapped phase splitter, feeding two grids in my balanced tubecircuit.
after alot of experimenting i can know see alot of different things that could be of interest and i dont know if i should try to fullfill them all.
-terminate/zobel the secondary so that a squarewave looks like the sharpest squarewave ever.
-do a XY scan and see that the phase curve runs somewhat smoothly and reach 180º with out to much fuzz.
-same as above, but see that the phase curve looks similar on both ends of the secondary and that 180º is not found an octave or three from each other.
-do a sweep looking at both pri and sec and see that the loop gain is more or less steady before it falls.
in my tries of getting a nice result, its hard to get all of theese stuff lined up. feels like i have to sacrifice something...
am i overthinking stuff.
what should i focus on?
is a sharp squarewave on the sec trivial?
