I am repairing an Anthem PVA-2 power amp. one emitter resistor was not installed correctly leaving it dangling from one lead. that meant only one output (of a pair) was running and of course it finally blew. Now I have it running again but the protection circuit still will not pull the relay in.
SO, I am looking for schematics. for any of the anthem solid state series may help if they used similar protection circuits??

hi did you ever find a PVA schematic? I have a module I've repaired and is working but the protection circuit is not activating, and I really really NEED a schematic. Badly. I've invested a LOT of time into it, and repair is not cost effective otherwise. Your reply would be appreciated, thanks!I am repairing an Anthem PVA-2 power amp. one emitter resistor was not installed correctly leaving it dangling from one lead. that meant only one output (of a pair) was running and of course it finally blew.
