Fred, >From previous threads, I suspicion not, but..... In tune, does drive cause current to increase? Or in PTT, drive and whistle increase current? If so, look at the relay contacts.

It shows idle current only when you go to tune or hold the PTT on the mic. Any ideas where to start. Tubes or power supply? Power supply rebuilt 3 or 4 years ago .After rebuilt it always had a 60 cycle hum on 40 meters. You could feel the cabinet vibrating.
