I may build one with the new source for transformers I found... the ones in the latest amp I built really impressed me. Great tone, heavy as hell, and really nice quality.

Charvelguy, Pete thanks for the infos !

As far as the small wattage high gain amp goes. My self-build amp is based on the high-octane from AX84 which is advertised as a high-gain amp. It has a nice sound but i wouldn't call it a super high-gain amp. Nothing near a Überschall for example. I still run my digitech RP3 in front of it.
However there is a modified version of someone at ax84 where a third gain stage is added to the high-octane. Infos here:

I never heard this version but maybe it's a nice starting point in terms of a high-gain amp.

If you look at the schematics though, just about every high-gain amp is a variation on a marshall. The tone stack is after several gain stages, while the fender/mark series boogie has the tone stack early. That's why on the mark series the tone controls really do weird things and interact so strangely together.
