For the first time ever, had one of my PPX go down last night. 1600 on bass. Lost one channel, clip light constantly lit. Fearing the worst swapped a cable and ran both subs off the one channel. Carried on for about 30 seconds more then click! No more bass. Both clip lights lit. Could smell something was hot so had a look with a torch and saw the fan wasn’t working and realised it had overheated and cut out. Managed to get a desk fan, gaffa taped that round the front of the amp rack. Felt like the heat from a P3000 out the back! Left it for 5 minutes, switched it back on and away it went again! Carried on all night like that no problem! you can depend on your PPX that’s for sure!

Thermal switches! Also, while you've got the top off to fit the thermals, check the caps for bulging. Had a 1200 that did that and it kind of roasted them!

Yeah I’m expecting the thermal switches. Undecided about replacing them or just re wiring the fan to run constantly.

Definitely. I can’t see any of these modern amps still going in the future like a PPX does.

Probably best to wire the fan permantly on as it's a 1600 Gaz, you wont get the same problem again. Get really hot these 1600's. It wont do it any harm having the fan on continuely.
Be seeing you.
