I have a pair of '80 Heresys. One of the K77 tweeters quit working. I opened the back and checked all the connections and they look good, nothing loose. I disconnected the tweeter leads and hooked the speaker wires directly to the tweeter and it makes sound. So I hooked it back up to the crossover and it works fine for a while then goes out again. Anyone know what the problem is?
Thanks,
Ed
