Default Ampeg BA115 keeps blowing fuses

Has anyone on here ever worked on one of these amps? Problem is that I can't get any voltage readings anywhere because when I cut the amp on it keep blowing fuses. Any input is much appreciated!!

Blown (shorted) output transistors. With an Ohm meter (power OFF) these will read something very close to 0. Drivers can be damaged too so don't just drop in a new pair of outputs and fire it up.

Less likely it could have blown the bridge rectifier instead of OR in addition to. Bridges are more likely to fail _after_ the power transistors because some yahoo installs a 15 amp fuse and blows out some more parts.
