Maybe remove the tape player and turntable to see what's going on under there?
I've been under it, but there is something anchoring the top to the front at the front in an inaccessible location. I have two and im almost ready to sacrifice one just to find out.

Update: Got it all working/stripped and de-faulted.
Whats the policy on posting a bunch of informative photos on disassembly? (And bragging a little?)

OK. So I'll do a little Photo Essay on getting the Pioneer MS-6500 (Turntable, tape and receiver) NOT the M-6500 - that's another product and a different Schematic.
Here's the unit:

The next two shots are of what I thought were balancing screws to level the deck - nope. These are catches to ensure the table remains in place. This is my first turntable repair, so you may have seen it straight away. I took a while.
The first photo is a close up of the offending 'locking screws' - loosen and move toward the centre of the platter to unlock.

The centre screws under the turntable that attaches the top to the system. Bloody little buggers

Of note with the faults - as usual, most caps could be replaced, but none had leaked or had any signs of corrosion or bulging. Ground to framing just next to incoming external source voltage had visible signs of heavy corrosion. Resoldered and tested for ground fault and continuity throughout.

Awesome, thanks for the photos. I’m trying to work out the belts for the cassette deck, would you be able to suggest what and where please? The spindle off the motor spins, but....
