Peavey schematic required

[philly]

Hi All,
I am helping a friend out with his totally dead PVXp12 power speaker.
After initial inspection I discovered that it runs a switch mode psu so I now require a schematic .
Maybe someone could post one here or PM me. I have tried all the usual sources but no luck.
Thanks in advance.

Thanks dmeek for the schematic and greetings from Ireland.
Just saw your reply now.
Now the fun begins.

Thanks for your reply.
That was going to be my plan B but thanks to dmeek I am now sorted.

UPDATE,
Printed off the diagram supplied by dmeek and went checking some voltages in the Psu area. Before I received the diagram, I had established that 330V dc was present at the main psu switching transistors. For some strange reason the unit came to life, the fan started running with both led's on the psu board illuminated. There was a hum from the speakers also. I straight away thought ''dry joints'' so I tapped all boards hoping to narrow down where the problem might be. With boards installed again and all screws tight (as one provides grounding on the psu board) the unit is now working. At this stage I have re-soldered all the psu board as transformer legs are the first port of call when checking for intermittency.
I welcome any comments.

### Returned to it this evening and tapping the rear input board caused drop in audio level with hum. This turned out to be the contour switch at the rear. I will soak test over the next few days.
