Working on a Hertz HDP4 amp. It uses the IRS2092S driver ICs and IRFI4019H outputs. The outputs are dual mosfets and they use two in parallel on the output of the driver chip. Hope someone can answer a question on this design. I had two shorted outputs. I pulled them and powered the amp to test the driver chip. To see if I needed to replace it. when I powered it, the IC popped. Retested and had two more shorted outputs. I pulled all the outputs to test. When I powered the amp it popped the other three driver ICs. Is this normal for this design. I would think you can pull the outputs without the driver ICs burning up. Can anyone offer any insite on this? I can post pics of amp if you need them.
