They appear to be the secondary snubbers. Did you remove them to see if they read open or gave you some sort of resistance?
Are the caps shorted? They look like they overheated.
As a side note, these are not critical to basic operation of the amp. The amp should work without them.

The voltage would be in the mv range. If the output stage is the problem, the current almost certainly has to be flowing through the output transistors.
If it's not clamped down, check the heating of the outputs to see if they're heating up.
A current limiting resistor typically works better than the limiter in a power supply.

What work have you done to the power supply?
Sometimes letting it draw current for a few seconds lets components in the problem area heat up and can help with troubleshooting.
Have you clamped it to the heatsink and powered it up with no limiting to see if the current draw was simply inrush?
