Finally got back to it, and tested all the preamp TO-92 transistors. At least one of each pair were faulty! I found the equivalents, installed them, and it lives! I removed the limiter and connected to A/C, and played my guitar through it, sounds OK.
I now need to modify the Special 112 rear cover/heat sink to fit, still debating whether to add more cooling fins, (the Special 130/150 are a lot larger). I can leave the footswitch jack, but need to lift the pre out, and power amp in, because of the spacing. I may just jumper the power amp jack connections, and forget about them. Since there are holes for speaker jacks, I'll use std. switchcraft and take advantage of them. They are marked 4 and 8 ohm, so I assume the 112 had a transformer output, parallel will have to do.
