There are alot of these amps in use in movie theatres in my servicing area and we are starting to see many failures of them. Some have had shorted bridge rectifiers and some just seem to drop a channel and the result is no output, but that channels circuit seems to be operating just fine. Most are about 10 years old and many of them use the built in QSC X-over card as most of the systems they're in are bi-amped. I'm getting tired of sending these back and forth to either QSC or the local service center and would prefer to start repairing them myself to effect a faster turn around and less service trips to remove end then install a loaner amp and then re-install the customers repaired amp and so on.
Has anyone out there that also services these amps seen any common problems with them... cap failure, output relays bad, solder problems, or certain parts of these amps that commonly give a headache? They are certainly beginning to cause some big headaches around here!
Thanks in advance for any suggestions on this......
