It started making a clicking or popping sound. And it starts after an hour or so after a cold start, when it has cooled down. The sound sometimes stops after a while, and then start again. I read here on this page that a relay may be faulty. Does anyone here know what I need to do to solve this problem? ps audio power plant premiere
Welcome to the forum @RocketMan75
I had a P20 that would make metallic sounds when starting up from being completely off and, to a lesser extent, when cooling down after running for some time and then being shut down. I attributed the sound I was hearing to thermal expansion/contraction. I’ve had cars exhibit similar behavior when shut down after a long drive. The metallic P20 sound I would hear had no impact on the system’s sound as it wasn’t in the signal path and it went away quickly. If this is what you are experiencing, it’s nothing to worry about.
I had thay happen to mine years ago and it was a bad regenerator. Check the THD out.
