Excellent proper use of a ferrite bead on one leg of each device.

We exploded a coffee mug full of fets before we found some that
survived. The power rails on this amp can go as high as +-200, and
peak output current is 120 amps. I don't really like doing big, heavy,
explodey stuff like this. The power transformer weighs more than my
smallest employee.
