So. The Zeners came yesterday (50 pcs for $1.50 plus $3.25 shipping). Today I installed it, check the 10.5V and it was exactly on the spot.
The CD worked with it being 8V, I guess it might be the VCC for some op amps and usually there is some margin plus common mode rejection for the power supply is anywhere from 90 to 120dB (didn't bother to check the datasheet...it works).

Anywho. I connected everything, and upon the button press the CD tray happily, easily, without any help rolled out.
I took it to the stereo setup, and it played just fine.
I need the remote to control the volume, the player came without it. I could buy a generic replacement for $13, or try to get the real one, which could, with shipping, easily get to a $100.
But so far I use the fixed output

What I thought was the volume control is indeed it, but for the phone output.
The potentiometer is bad. It is really scratchy, with some dead zones....and there is no good way to deliver the Deoxit inside, the diameter of the bushing being small. Right now I don't care as I don't use phones. I will explore where to but a new one....willy-nilly, not a priority.

So, to recap:

1. The table roll-out fixed (the  ew PRB belt), Lube and all also done.
2. The dent in the back and the consequences are removed.
3. The bad connections are fixed across the device (Power, Main Board, Phones board).
4. The incorrect +10V  voltage (8V) fixed by replacing the bad Zener.

   



When I buy the remote, this thing will be complete.
