Sunn Coliseum Lead Amp schematic

[rove]

I have a Sunn Coliseum Lead Amplifier, recently acquired. the amp works fine, but I am hunting down a schematic for 2 reasons: 1, The Master Volume pot, though functionally fine, has had the threading knocked off of it and it sits loose in the chassis, so i would like to replace it; and 2, the footswitch attaches via rca jacks, but does not follow a "normal" wiring scheme (ie my music man and another on/off footswitch have no effect) or is possibly simply broken, so I'd like to see how the wiring works there.
I asked about this stuff on the Sunn newsgroup, but have not had any luck. Right now I am thinking I will just take out the volume pot, measure it, and order a replacement, taking careful note what wires went where (stupid digital camera is broken). any help is much appreciated.

Is that amp loud?

"what?"

Who played a Sunn. Was it Leslie West?

Thanks for the schematic link. Unfortunately my particular model is not in that list, but the Coliseum Bass and a couple of others in the coliseum category are, so maybe that will get me the info I need.
Loud is an understatement, I truly don't have the cabinet(s) to do this amp justice. It is about 3 ft wide, taller than my 410 combo when place on its side. I think maybe entwhistle? don't quote me on that but I think the Who had a few of this era (mid-seventies solid-state powerhouses) Sunn amps in their live setup.

Maybe it was Hendrix.
But he plugged everything.

I remember reading Hendrix endorsed Sunn for a while but didn't like them. Went back to Marshalls.
