HK Tubemeister 36 schematic needed (not 18!)

[Nyqusit5]

Hi all,
I have a Tube meister 36 in for repair. It lights up (front panel) and the tubes are powered, but the channel selection and "automatic" bias system seem off (no led lights up at any time, except for the blue plexi faceplate ones). To put it differently, the yellow leds inside the chanel buttons do not light up, and pressing the buttons has no effect. The amp passes no sound. It seems that there is a problem with the low negative suply voltage (-15V), but some components have the supply (like the first op-amp).
The amp is quite different from the Tubemeister 18 (schematic on this forum) in the preamp and low voltage rails sections, and it uses a mix of standard and smd components. I have gone as far as i could without a schematic so I am asking: has anyone got the 36's schematic? Please?

I'm not sure if this will help, but here's what I have.

It seems my last post didn't compute (?). Or I forgot to click Post.

Anyway, thanks a lot Drewline. The PA looks closer to the TM36 in designa but it still is quite a different amp.

So I am still very much looking for the schematic of the Tubemeister 36!
