I put my cary tube amps back in the system and the problem is there. I have tracked it down to the preamp. I tried changing tubes with some extras I had, no help. With the cover off and a power line glove on, I moved the line stage tubes just a bit and the hum changed with every tiny move. I swapped a SS preamp into the system and the problem isn't there so I am going with a problem with the preamp. I tried switching the speaker wires as indicated and that didn't work. I also tried as suggested to power up the source and allow the preamp to come out of standby before powering up the amp and the problem is still there. The only time the problem goes away is when intake the CJ PV-7 out of the system completely. I guess I'll send it back to CJ to have them troubleshoot it. Could it be just a bad tube socket? The preamp IS 30+ years old.
Thanks for all the help
