The amp will not power up. It doesn’t even draw any amps and the protect light is not on. Thanks

Is DC voltage making it beyond the remote connector? They often have bad connections.

Is the driver IC producing pulses when you apply remote?

If no drive pulses, the voltages on all terminals of the LM339 would be helpful.

Hi, Perry it looks like I had a broken remote wire so I was not getting any DC at the remote connector. I will fix the wire and continue to test thanks for your fast response.
