I’m trying to fix this pair of JBL 4301B that I had fr years and only now could afford the missing tweeter. But now one of the woofers is giving me trouble too. I know I am not doing a perfect job because there’s LOTS of it I don’t understand so I do as I can. But can I leave the sound on to hear what’s happening? Should I wear gloves not to get an electric shock? Thanks guys!
Really bad idea. Protection circuits on an amp protect the speakers, not the amp. By the time the protection circuit detects an overload created by you shorting some wires and energizes the relay, your finals will already have been fried.
