I recently learned of the wonder that are peaking coils. My TV also happens to be a Motorola, apparently they used these components more so than other manufacturers of the day. I was going to try to swap out mine when I'm home for spring break in a few weeks but now it looks like that won't happen.

The answer is modern equivalents are available and they aren't particularly expensive. You could try swapping in some of your mystery coils, I don't think you would hurt anything. It would just be a waste of time if none of them work. Personally I would opt for new substitutes or NOS originals if you can find them. As far as acquiring a schematic, ask Tim (Kamakiri). He was kind enough to send the one I needed to me, for free. Good luck.
