Does anybody have any schematics/ideas for a high wattage solid state amp that would be compact and light?  Woods builds tiny amps with insane power ratings.  I'm thinking 100ish watts for a cheesy bass rig.  I'm not too worried about eq;  I'd be happy with just a master volume.

Anybody have any schematics for any of Woods' amps?  I understand that he used to stick a copy of the schematics inside of every amp.

My first post, and I want to tell you guys that this forum rocks!

IIRC, there's W. Woods patent which shows a schematic.  Really it's a straight forward amplfier.  There's may circuits similar to this and most of those small bass amps use similar circuits - even high end ones.  The trick to making it small is to use a toroid transformer and getting the heatsinking right - many use fans and a smaller heatsink.  There's a few designs which claim to use switching technology and a few others which use multi-rail amplifiers (which keeps the heating down).  If you want to max-out the signal for a small amplifier check-out the Peavey and Fender designs which put a limiter around the power amp to stop it farting out when pushed.

Remember power isn't the only factor in getting out SPL's.  A single 1x10 is not as loud as 2x10 for the same *power amplifier* power.
