Power Acoustik LFA1-2000D. Long turn on delay time when the amp is cold. Two minutes or more. Anyone familiar with the turn on delay circuit. Amp is not in protect. Power led is green. It just takes a long time for the relay to turn on.
There are 2 versions (at least). I don't know which you have but be suspicious of any 3k resistors (marked 302). I saw several of those in at least two completely different amps fail. I had others fail as well. Yellow in the photo.
