VPI Classic hum

Got mine a few weeks ago. Installed it with a high-output Benz Ace H cartridge. Loved the sound but there was a hum when I turned the preamp volume past the 10 o'clock position. Later changed to a Clearaudio Concerto, the hum was quieter, but wouldn't go away no matter what I tried.

Then I read the manual closely, and it said something about using shielded interconnects. So I tried a pair of Rega Couple wires, which are made from Klotz cable, and are shielded.

And you know what, the hum just vanished! Now I'm at peace ...

Just to share with those have hum issues with the Classic. Do share your solutions.

Mike should know better. If not Mike, then Harry. It's Yiddish and mean obsessing about something to the point the victim gets a head-ache or very aggravated. The full expression is "don't drey my kupf." Don't give me a headache.

Wayne..., sorry I'm a little confused. In setting up VTA for the 2M, does this 2 degree adjustment mean the back side of the carty should be raised a little via the VTA mechanism. If VTA is raised that way, then the back end of the carty will ride just a little higher than the front end. So, if one could actually measure the position of the tone arm, it would not be horizontal. Instead, the tone arm would ride at a slight angle -- 2 degrees as measured from the stylus tip.

Does my question make sense?

Thanks for reminding this phrase. As being Jewish I should have known it. I am originally from Russia so know this expression in Russian but did not know its English variation.

VPI sent me a brand new Classic 1 table and it was humming exactly same way as my own. The cartridge picked up the motor noise. VPI exchanged Classic for Aries 3. It arrived last week. NO HUM at all with Aries 3 and the table is just amazing.
