Question Harrison K 3000 power amplifier schematics

Hello Everybody,

I'm trying to repair an amplifier from Harrison (U.K.) it's a pretty old power amp....

The model it's K3000 it should be more or less 600W RMS at 4 ohms,

The power mosfet it looks like good .... I did't look at all....

I'd like to find the schematics because inside there's 4 little boards with smd components with the codes scratched.....

Probably 2 of those are for the vu meter and the others 2 are for the limiter... there's 7 multiturn potentiometer and others components.... I mean.. it's a pretty complicate...
I don't see the polarization stage for the power mos and probably it's inside those little boards.

If someone can help me I'll be glad to share the experience in this "mission impossible"....
