Help, please!
The amp built into the subwoofer of my beloved L212s is constantly blowing its power outputs.
My repair shop of choice here in Portland, OR has replaced them twice; the first set lasted about 5 hours, the second set three. The repair shop has now thrown in the towel and given me a full refund. Might anyone have a suggestion\scenario as to potential instabilities upstream in the amp's (circa 1977) circuitry that could cause it to keep blowing? At 90 pounds I'm hesitant to ship the unit to a more vintage-JBL-centric service center, but if thats what it takes, so be it. Any suggestions on the west coast?
Thanks!
Dirk
