Dave - I couldn’t reply to your message, since we’re not technically friends... so hopefully you check back on this page sometime.

yep, it’s a great amp, though I’ve not used mine much lately. with certain guitars, I’d record with it rather than my princeton reverb. about once a week I wonder if 1) I should upgrade the cabinet, or at least the baffle board - which is made out of 1/4 inch masonite I think, and 2) upgrade the speakers to some nice, efficient types. but haven’t got around to it, and if I were to gig the thing, I’d need to put a grounded 3-prong plug on it. ANYWAY, about the schematic, I found one in Pittman’s "The Tube Amp Book, 4.1th Edition". It’s pretty grainy, but at least it’s a start. If you can’t track that down, or a scan online, I could take my book into the office monday and scan it for you. let me know, and good luck with it.
