Greetings everyone. I re-capped a pair of KLH Model Five crossovers but on one of them the 7,000Hz attenuator switch cuts out in the High position and I get no sound. The Lo and middle settings are functional and everything else works just fine.
I've checked the schematics and everything seems to be wired correctly. How can I troubleshoot this? Do the switches go bad? I tried cleaning it with contact cleaner to no avail.
Also, for what it's worth, this switch looks different than the other three, like it is a replacement. It has an opaque plastic cover and the others are clear. I was unable to upload an image. Perhaps, it has failed before? One of the tweeters was not working when I got the speakers which I narrowed down to the crossover network but am not sure if it was this particular crossover, as I lost track.
Any ideas or suggestions?
Thanks,
Carmine
