Burnt gar2520

[Trench Recordings]

Looks like I burnt two gar2520. It was a mistake I made in the PCB wiring.

Anyways, are they garbage or can I repair them ? Where should I start to look?

I just fixed one I burnt as the result of miswiring.
What was the wiring error?  Identify the components that got hit and replace them.  It's probably not more than 2 or 3 things.

Then double check voltages before putting the op amps in.

I believe -16V was sent to the out pin. They smell alittle burnt but visually look fine
