VPI Classic hum

Vinyl ..lover, both the DV and Zepher are shielded and I haven't noticed hum from either carty. I would circle back to your dealer. He should know what to do. But if you get stuck, try a Dynavector or SS VPI Zephyr.

Good luck.

Bifwynne,

I emailed Mike from VPI and he responded back saying that the problem should be resolved by proper grounding and using shielded interconnects. I have a ground wire running from the table to phono stage and using JPS Labs ultraconductor interconnects that the dealer confirmed they are very well shielded.
Thanks for reply

Vinyl_lover, did Mike's suggestion help? It makes sense.

After several tests that Mike asked me to do with VPI, he diagnosed the problem. Either the cartridge is picking up electro-magnetic field from the motor or some mechanical vibrations. I've shipped the VPI base unit to him for repair.

Vinyl Lover31,

I am also getting a hum from my VPI Classic 1. When I touched the Interconnect at the junction box on the TT I get the hum, and also touching the interconnect at the phono stage I get the hum. I ground the TT to the phono stage and also to the preamp and I still get the hum no matter what combination of ground I use. My interconnect is from Audio Art Cables, and I confirmed with him that the interconnect is shielded. I also tried several different interconnect and I still get the hum. In taking it a bit further, I tried two other phono stages in the system and I still get the hum when playing a record or not playing a record. As a last resort I wrapped a piece of aluminum foil aroung the interconnect and the ground terminal on the TT junction box and the hum was reduced significantly. I have to turn up the preamp about 70% to hear the hum. I do not think this is the best way to solve this issue, so I am still up the creek. I will give VPI a call. Anyone tried the VIP phono cable yet or any other phono cable?
