Mesa Boogie QUAD preamp

[Colas LeGrippa]

Hi,


Juste came in a quad preamp from Mesa Boogie wired for 220V. I can't find the power transformer wire colour code in the schematics. I have to wire that thing for 115V. Tanks for information

Can't find any power supply schematic

Look and read here , it is for a Road King . Are colors are same ?

Should be able to verify primary tap with multimeter set to ohms.

I have the Studio Pre pinouts. It's very similar to the Quad but not sure if they use the same transformer.
