I pretty much finished the rebuild and wow does it sound excellent. The noise level is very low. Only when it's turned way up and the room is very quiet can you hear some faint hum and hiss. Just as quiet with my TT connected!
Thanks to all for the great advice. I've learned a lot on this amp. Special thanks to Jim for all his help.
Now on to my next project. A Trio W-45
