Toggle switch cleaning?


I have a preamp with a toggle switch for changing phase. Sometimes I lose the left channel on switching. Is this something that can be cleaned at home, simply and safely? Or can this be worn out?Thanks. Pete

Yes indeed 😄 pop the cover on the DMC 20 and send me a photo closeup of the relays and I'll reciprocate with a link to a direct drop in replacement.

Good listening
