I have a Trace Elliot AH250 from the mid 80's - it has the GP11 preamp. It's all solid state, puts out a very healthy 250 watts at 4 ohms, all solid state yet it has a very warm tone, it's loud, has a very cool black light, it's loud, it sounds very nice, simple easy to use controls, it's loud... did I say that it's loud? I'll never part with this amp.
EDIT - I've played in some loud situations, for a while with two guitarists, one using a big Fender combo and the other using a Marshall half stack and a very heavy handed drummer... another time I played with a loud drummer, guitarist, amplified horns and the worlds loudest keyboard player - in both situations I had plenty of power with the "little" 250 watt Trace.
