Hi all.
I hope everyone is safe and sound, staying healthy.
So I have a AP1200 that is doing something a kinda weird, from a cold start it will play for 15 mins or so, then go into protect, and then out of protect, and then do that over and over a few times, but as soon as it warms up, say 30-40 mins, stays out of protect and works just fine.
Seeing as with the current state of the world, most shops are closed, so I was going to attempt at little troubleshooting on my own.
I am NOT a skilled electronics guy, but am a licensed mechanic by trade, so I can do mechanical repairs, visible wiring repairs and the like.
I do know how to use a multi meter safely and correctly.
I already have one AP1200, and I changed the fan in that one, no big deal.
Seeing as the Protect on this amp is mostly to protect against sort circuit from speaker load only, I am kinda confused. I am 100 percent positive the there is no shorts from binding posts forward, and I had the cover off the amp, and it is a short distance from binding post to board, so not shorted there for sure.
Cold solder joint?
I can supply the wiring schematic if needed, and I have the service manual.
Any ideas?
I know its kinda a tough one without having the amp at hand.
Thanks and stay safe!
Dave.
