These are potentially big fetish items, so I would definitely investigate the potential selling price on ebay before tearing the thing apart. These amps can go for $300 in "ugh" condition up to $600 for rebuilt. If you're talking about getting a pair of trannies and a choke and a couple of so-so output tubes and a bare chassis (that you'll have to do plenty more work to make "ampable") it's arguably better to sell it and buy some kind of amp (or, buy amp parts of your choosing)
I should talk, I guess. I got this Pilot SA-232 stereo some time ago for free. (I insisted on giving the fellow who gave it to me $20)
Really nice, oversized transformers. Amp is in pretty nice shape, but kind of covered with wax from blown up caps and the like. Anyway...I am doing a bare-chassis restoration. Tube sockets were...fragile, semi-scorched looking. The thing runs/ran hot. I should (have) probably just sold it, but it's a nice little package with the perforated cover and these are highly regarded.
Some time ago I got a Radio Craftsman 500 mono amp for $25 and I sold it for $685. It had a museum-grade matched pair of Genalex KT-66 that were just awesome. Within 1/2 mil of each other. Nice amp, but I really did not want to go hunting for another.
