Help, need a schematic for a crate VFX5112

Help, I need a schematic for a crate VFX5112. I'm not having any luck finding one on-line. Crates web site has a schematic library, but I can only find a footswitch schematic for this amp.
thanks

Re: recommendations for next amp build

matchless lightning sounds great. build it with a pair of el84s or 6v6s. lots of gain on hand.

Re: Matchless lightning with el34's

I haven't looked at a lightning circuit lately, but wouldn't a el34 lightning basically be very similar to a marshall jtm45 circuit?
the non-reverb chieftain circuit is a good one!
