When you reference "ones that are usually bad" I assume those are the paper caps, which is not something I've dealt with before since the monitor work I've done has been in the era of mid 70's into the 90's, so that'll be quite interesting to me. For the electrolytics I like the approach of stuffing into the cans for the original appearance.
I agree on shotgun replacement, and that's a good suggestion on powering up after a handful of cap replacements. On arcade monitor cap kits I generally do the whole lot but I suspect working on one of these requires a lot more care. As for possible typos, I've read that it's good to note differences between the actual caps and what's in the schematics/parts list. The suggestion I read which sounds good to me whenever there's a mismatch is to stick with what's actually in there if it looks factory, go with the schematic value if it looks hacked, but in either case make note of the difference so you can try the other way if the first choice doesn't work as you expect.
This unit was supposedly working recently but if the caps haven't been changed before then I'm sure they're a ticking time bomb. The prior owner was a young lady who is certainly not technically inclined, but beyond that I don't know anything of the history of this unit, other than that it appears to my inexperienced eyes to be well cared for.
Thanks for the tips on the possible picture problem. I will definitely check that out once I am ready to start diving in.
Thanks also for the tip for the turntable.
Yes, the radio works just fine.
