Belts came... new power ICs installed, boombox reassembled. Forgot to put the push buttons from the sub-chassis back on, and the counter belt.

The bad:

Deck 2 hums when the buttons are touched, and crackles. I cleaned all the other switches at my shop, haven't got any spray here. Sounds good once it works though.

More hiss than you'd expect from the deck preamps.

I have to take it apart again

The good:

It is loud. It sounds good. Deck 1 is quite good quality, I was nervous that it'd sound dull and warble, but it sounds bright and the speed is stable.

I know how to take it apart

One thing I've noticed, the tape preamp ICs are kind of noisy. Has anyone played around with lower noise sip opamps in boomboxes? I'm thinking even a 4558 might be an improvement.
