schematic / info needed for Coliseum Slave

[Dave Brown]

I'm trying to fix a Coliseum Slave for a friend.  All the
outputs are fried.  They're simply listed as a 22-3773 which
I assume is a Sunn P/N.  They're Motorola TO-3 power transistors
with 1974 date codes.

Anyone got a cross reference for this or a schematic?

Thanks.

Dave -
I too am attempting a fix for a friend. Bought schematic from Fender ($5). But no service information included, like how to set the bias properly. Thought I had it done after replacing defective filter cap(s); couldn't get any real power out of it, though, then it ran away and destroyed my test speakers.  Sittin' on the bench still...

The power transistors are 2N3773s, probably have to look up substitutes now.

Email me if  you're still working it.
