Severe Static/Slight Hum SME 20/2 w/BAT


I using a SME 20/2, SME IV.Vi arm, Lyra helikon, hovland music groove XLR, BAT VKp10SE phono setup. (system posted here) I have a slight low level hum. I talked with Wally Malewicz yesterday. He thinks my xlr arm cable may be the culprit. I also have a bunch of static issues, which is where the discussion started with Wally.

Zerostat'ing barely reduces the static. Sometimes it literally glues the record to the platter with so much electricity.

Before I go buy a new arm cable, any idea's on troubleshooting the grounding? Or other idea's I should try?

Thanks very much! John

Thanks all. I have a ground wire from the motor I which is on rubber mounts, and a ground wire on the upper plinth, which is where the bearing is bolted on. These 2 ground wires are grounded via the power supply for the motor. So, I took off the plinth wire and used a jumper to the back of my phono stage (same ground as tonearm). Hum is the same, but I swear the static is better and there is less noise from pops and clicks. So, thanks TWL.

So, now it's off to trouble shoot the hum...maybe a bad ground somewhere like Dan_ed says.

Cylinderking_1, that's very strange you say that. The reason I bought this tonearm cable a year ago was the fact the Graham I had picked up all sorts of RFI. The Hovand eliminated it...not sure if it was the XLR config or a different grounding scheme. I was so happy to have the latin radio station not playing over my music, that I overlooked the hum. Now...I think I may try a 3rd cable to see.

Thanks to all.
