Mesa Boogie Vtwin preamp; PSU?

[Bernardduur]

Hey all!

I just got this Vtwin, the preamp version so not the pedal version, in with a problem in the PSU section. It is in the -12 V section of the unit (2 lines come into the preamp which are a B+ (250V DC) and a 17V AC of which the +12, the -12 and the +5V is powered.

Does someone have a schematic of the preamp version and then mostly the PSU section? There are some burnt resistors there I can't tell the value of.

Thanks!

Mesa is generally good about emailing schematics to individuals. I got the PSU and power amp to my old triple recto several years ago with little problem. You may want to try emailing them and asking for the schematics.

Thanks! I'll try that!
