Hi folks, wonder if you can help with a couple of service-related questions on a Trace Elliot Super Tramp guitar amp I'm going to work on for a friend.
1. Is there any service manual for these other than the schematics I already have? Would be nice to have voltages, biasing, tests, that sort of thing.
2. I saw mention of the Super Tramp having an EC83/12AX7 preamp tube. There's no tube in any schematic I've seen. What's with that?
I don't have the amp in hand yet, just a description that it sounds squawky or something. So I'll need to do the usual tests. Anyway, if anyone can help clarify those two points, much appreciated!

Service manual? DARN few guitar amps of any brand have a service manual. Schematics are it. And really, the circuits are not generally that complex.
A bunch of amps stick a lone 12AX7 in the preamp - kinda gives it that little tube-iness of joy, y'know? But I don't see one in the Super Tramp.
Actually the SUper Tramp has a "manual". It is two pages of the schematic plus a cover page with the title.
