Fleetwood model 4068... Advice?

[VintagePC]

Does someone have _definite_ specs on the cartridge? It is a TC8S, with (as mentioned, TC8G and TC8RS styli). Some sites say stereo, some say TC8 was mono, etc. etc...

It seems to be wired for stereo, with one of the three pickup wires being a common ground (bridged at the terminal block under the turntable), with the other two going to the center pin of the phono plugs. Yet another site suggests that there was one wire for each needle... Very confusing.

Also: there's an adjustment screw at the top of the changer tower, under the tone arm (in the block that holds it to the shaft). What is this screw for (visible in lower left of image 1039- perhaps auto-return trip point adjustment)? I _will_ need to remove that spring assembly from the shaft at some point, how critical is it to get that back to that exact position?

With regards to the rest of the set: Once I finish the turntable, I'm going to re-stuff the electrolytic multi-cap. do I still need to do the others, because they seem to be plastic/metal sealed (and not wax/paper). There's a better chassis shot in the last bunch of photos.

I'll also be checking the resistors and replacing any that are out of spec so I can get them in with my order of caps.

Sorry for all the questions I'm not experienced in this area at all, but I'm fascinated by this stuff and can't learn enough- there's something awe-inspiring about watching the intricacies of such mechanisms at work.
