One more question about the Concertone.
I installed a 4:1 output transformer and now the output headroom is way too low. Without the transformer, it just barely starts to get a bit of harmonic distortion right before clipping my AD converter input.
But with the 4:1 transformer, it's totally crunched at around -3dB or -2dB before it even sees the interface.
Any "easy" fixes to squeeze a few more dB of output headroom out of this circuit? (Attached)
P.S. Another odd situation is the 12AU7 meter buffer circuit decreases the output headroom even more when engaged. I mean, it's like a fuzz box.
