Fairly recently I had buzz that I thought coming from amp. When I brought it to my lab, there was no buzz when connected and hooked up. I literally checked all of my main system components, but it turned out the light bulb that was buzzing very loud. It's one of those crappy energy efficient coiled one. Definitely they're not 'audio grade' ones. Replaced by 60cent regular light bulb and problem was fixed.
Some noise issues with my new VPI Prime
Hi everyone,
Was fortunate enough to purchase a dealer demo VPI Prime. Have been enjoying it for the last week or so - it's a wonderful sounding table. However, I am having a couple of noise issues with it. It's still under warranty, but I was hoping to find a home cure if possible. There are two issues:
1) Motor noise. This is from the mechanical operation of the motor - it doesn't change with volume of the system, but it's audible during quiet passages. The motor makes a slight buzzing/rubbing noise with each rotation. I am guessing that some lubrication is all that is needed. I've tried setting the motor on a rubber pad, but that doesn't make any difference.
2) Buzzing from the tonearm wire. I get a buzzing that increases with the volume. By 50% on the volume dial it is quite pronounced (you can hear it from the next room). It is coming from the wire that runs from the tonearm to the Lemo connector on the junction box. If I touch the wire, the buzzing changes as I move the wire around. If I raise the tonearm very slightly off the unipivot spike, the noise becomes extremely loud. I tried to wrap some tinfoil around it, but that didn't make any difference. Could this be a defect?
Any thoughts on some simple fixes that might address these issues?
Thanks,
Scott
