Interesting idea wobbleu... I have some copper tape around here somewhere I could try. Although I'd rather not modify the cartridge if at all possible.
I've managed to get the hum a little quieter by unplugging practically all of my other equipment. Honestly, I am amazed at how susceptible the cartridge is to other equipment as I figure my setup is no different than most.
Just some other tidbits of info that could maybe help out:
- The hum is much stronger on the left channel.
- The cartridge picks up a significant amount of interference from the motor when the TT is running. Do people have this problem with other carts?
- Disconnecting the cartridge and shorting the tonearm wires (L- to L+, R- to R+) results in practically no hum. Using an older cartridge (Shure M91ed) results in practically no hum.
- The only thing that truly makes a difference is physically moving the turntable. I hooked up a very long set of phono leads, cranked the volume, and walked around my room with the turntable. I managed to find a place where it was quietest, but unfortunately that place is not practical for setup purposes.
Anyway, I am moving in a couple of months so I am tempted to try and ignore the noise and hope that it won't be so bad in my new place.
Thanks for the input folks!
