American Bass 750.1

What would cause this issue ?

The amp keeps burning the trace from the B+ to the power supply driver board

It burnt it up before the drivers and if you look between the drivers you can see it burnt there also

Hey caraudioguy, sounds like you have failed driver transistors.
If one or more driver transistor are leaky or shorted, when you measure between b+ and gnd you read OL, because the failure in driver transistors are a separate thing, but when you apply the power (without remote) a failed transistor try to turn on one or both FET banks togheter and of course is like a direct short throug the transformers.
