That could indeed be useable! What kind of power tubes are in it? Some of those old PA heads had the schematic stuck inside on the bottom cover. A pic of the schem would be cool to have.. Over on Thundertweak there are a couple of dukane schems. By the looks of them you may be able to create a Fender twin out of that baby. The one I was scoping out had 4-6l6gc outputs and a long tailed pair PI, and dual 5u4 rectos. That's half way there!
