In one of our buildings we have a Simplex 5120 paging/bell/clock system. After an electrical storm there was a full time "wop, wop, wop" sound through the speakers. The Simplex tech diagnosed a problem with one of the boards--blown diode. The prices he quoted seem to be outrageous. I've been looking for replacement boards on the Internet with no luck. Does anyone here know of any suppliers I should check with?
Thanks,
Terry
