Cleaned this up some more and got 50% of the noise to go away. Doesn't get noisy until volume is half way up. Not too shabby. Not my favorite sound. Will work nice in garage with old JBL 2500s.

The 2sc458 transistors might be causing your hiss, according to many posts on audio karma they are prone to failure.

Swapped it into main rig and it gets weirder. When the TT is running and hits the run out, the amp is pretty silent. As soon as the TT shuts off, it's a snowstorm.

The AUX is pretty quiet, the tape inputs (with nothing connected) are crazy snowy.

Satisfied for now, it'll get some use as is.

Sir Thrift-a-Lot:
Maybe there is a bad grounding issue somewhere inside.

Without the bottom cover on while sitting on the table I got it to act like a theremin. Waving my hand over certain spots would increase the snow. Doesn't occur with the bottom cover in place.
