Need Hafler Pro6000 schematic

[slowhands]

Trying to revive this and it is unusual enough that I need the schematic for debug. If some kind soul has this one (it's not posted on their support site), I would appreciate it.

I don't have the P6000 but the P1500 and P3000 use the same manual and schematics. Is it possible it could basically be similar?
If you think so, I have already downloaded the P1500/3000.

No, not similar despite the name similarity. P1500 is closely akin to all the other Hitachi lateral MOSFET amps.

The PRO6000 uses vertical MOSFETs in an array Anthony Holton would have been proud of: 16 per channel, on a wind tunnel heatsink. That's what I meant about significantly different. The entire amp, both channels, is on one rather large PC board, roughly 16"x14". This includes a preamp with unbalanced/balanced input and bridge switching and some signal level and fault monitoring and shutdown.

Right now the current rises very rapidly as I increase the line voltage, but not fast enough to make me think it's a short. Since this is all one board, I can't isolate channels and I can't partition this easily for debug.

If I can't get a schematic, I can still use the chassis and power supply. It has forced air cooliing, an 1800 VA toroid, and 2 42,000mf 100v caps that are all fine. Do you think this would be all right for a Zen amp?

Hafler Technical Support replied to my request for schematic with:
---------
Thanks for getting in touch with us. Unfortunately, after much
searching, we are unable to find a schematic for the Pro 6000 for you. All that I have available to me is the manual. Please let us know if we can do anything else for you.

It's apparently an orphan from the early days of Hafler Rockford. Oh well, Zenquito here I come.

response frequency- 1Hz- 300.000HZ +_ 0.1DB.
Damping factor- 20-500hz- 800
Slew rate- 100V uS
all resistor's metal film 1% Vishay
All cap. Wima MKP10 and black gate eletrolitic
