This amp came in with a blown PS and shorted outputs.Power supply is up and running but the high side FETS getting warm fast while the low side stays cool.
I replace two of the transistors driving the high side but no change.
What usually goes bad on this driver board?

The large transistors often develop bad solder connections.
Is the rail voltage staying constant (positive and negative) when you drive power into a load?

From what I've seen, one group gets warm and the other group of outputs get a bit warmer at idle. I've never seen one group cool and the other hot.
What's the idle current after the output is enabled (has rail-rail oscillation)?
