Nop, not a licensed tech or anything... i consider myself a good tinkerer and good with a soldering iron, but i could never come up with the slightest idea on how to mod a tube amp.
That's why i'm waiting for some mod-kit to come up (with instructions), that i can manage. BTW, i'm aware of the dangers involved in tube amps, and know the right proceedures for a proper drain.

Schematics i don't have but i'll start working on getting those (never dealt with Crate people).

As of now, i only have some pics of the amp's board (if that gives any help).
