Well I'm back at it with my 3rd M70 build. This one needed cassette deck work and treble potentiometer repair. I saved another one.
Here I have the pot removed from the board using my new soldering station. It made this much easier.

It's back together after repairs. Plays and looks like new during my testing. Installed new belts and fixed the treble on the the tone board. Cleaned it up and it's now 100%.
Video is prior to cleaning as I was sorting mechanical repairs first. This was the first test after all adjustments and repairs. Moment of truth time.
