The surgery appears to be a success. Patient is resting. Will take her out and stretch her legs tomorrow.
I couldn't turn it up too much because kiddo was sleeping by the time I got finished wiring, but from what I can tell, it sounds good. Might not even need new tubes or a new speaker too badly right now.
Tubed were biased way too cold, and the tone stack was fucking useless. Sounded like an icepick before, and sounds full and warm now. Not bad at all for $60 + 1 hour of work.
