I have a question about a amplifier with a tube keying circuit. :headbang The relay got bad so I ordered new ones with the same specs. When I put them in, it keys up but won't unkey. I put the old relays back in and they still key and unkey perfect. I though maybe I was getting some kind of bleed so I put a RF choke in line with the power for the coil of the relay,and that didn't help. I tried tightening the spring on the relay and that didn't help. I'm out of ideas can any one help?
Or could someone post a scematic and parts list of a 12v transistor keying circuit I can put together and replace the old one.? Thanks!......Tim
