How about a tube pre-amp like an Alembic F-1X?
It is 1 RU, has the simple volume, bass, mid,treble knobs and bright / deep switches, built in DI and return loop. Run it through a QSC PLX amp and you can have up to 3600 watts in 2 RU at 2 ohms. I use a PLX3602 that weights about 24 pounds. All said in a rolling rack case it's about 30 pounds. I frequently play through powered speakers and don't even need the power amp, but still get the tube tones of the Alembic.
