No clue. Part of the problem is the heads overheating. They have tiny
fans on them which are completely insufficient.

It's about two six foot stacks of speaker cabinets. Take a look:

You can see the amp heads piled up on the left stack.

Actually, he hasn't had that much trouble since going to 3000 watts.
At 2000 or so, he'd put everything on 10 and have a head fail almost
every show. (Mostly overheating and getting better a few hours later,
occasionally permenant damage.)
