Hello Everyone.? I am in the last steps in restoring a TR-4C.? I have found that on 20 meters, at 14.250 MHz, when peaking the Rf tune, I can get somewhat better stronger signals.? BUT, I get much better reception when adjusting the PLATE TUNING CAP to about 7.? When I adjust plate tuning to a lower value, I lose all signals on the band.? I don't think either the plate or loading caps should be interacting with receiver performance.? I have done just about everything in cleaning up the radio, tube checks/replacements, deoxit, and other items, except for an alignment.? Has anyone ever experienced this type of thing?? I have never seen this in all the drakes I have restored.?
Many thanks to the group.....you have helped me countless times in the past!
