You might also want to try making sure the cartridge clips are tight on the phono cartridge. Use a needle nose GENTLY and close them down if they are loose.
Hum in my system; its the turntable R and L interconnects. Huh?

I have a very pronounced "Hum" in my system, sounds like a 60cycle hum. I tried all the troubleshooting steps; it originates in the EAR, which has just recently been serviced and has new Goldline tubes. But here is the kicker, if I disconnect the R and L TT interconnects the hum cuts out and I get a fine white noise sound of much less volume. The TT produces the hum in the system even if the TT is unplugged from the wall receptacle. Removing the ground wire from the TT to the EAR has no effect. I can place my ear on the EAR case and hear nothing, dead quiet. A fault inside the TT?
