Who Is It in the So Cal Area that Fixes the Crown PSA-2XH?
The high speed fan on my Crown PSA-2XH had been coming on prematurely and perhaps the protection had been coming on, and I took the amp out of service a while ago. The other day I disassembled it and thoroughly cleaned it inside and out. The big capacitors checked out fine (measured at ~11,120 mfd, rated at 10,000 mfd). I removed the circuit boards and sprayed them clean with electronics cleaner, cleaned the pin contacts, cleaned the fan and filter, and used the shop vac and compressor to get all dust out. It really wasn't bad at all though.
Anyway, I put it back in service and it was working perfectly. Then a couple minutes later it "garbled" the fan kicked up, the overload lights came on, and I instantly shut it off. I left the top unscrewed so I could check the temp at which the fan goes into high speed and the boards weren't even warm. It drives my JBL W15GTi sub wired at 12 ohms. I pulled the inputs and output off and tried to turn it on. The protection instantly came on.
I seem to recall that someone local (maybe Pasadena area) fixed these and had even sent me a diode for it at one time in the past. Anyone know?
Thanks,
Todd
