Hi Euromut

I've just noticed you have something sandwiched between your MP200 and the arm?

What, why, and does it make a difference ?

(I have my MP200 on my Rega arm at the moment)

sorry for the long delay. Its a copper spacer. Helps with adding mass, and adjusting VTA. The combo of the arm and the Nagaoka, I needed a spacer.

So, due to the copper spacer, and the copper in the counterweight. I decided to take that and run with it.

No sonic improvement. Maybe the slightest bit of added mass from the plating.

After moving to a new house, I am getting some hum. I am going to be adding a separate ground lug (as some of you already suggested). I modified the housing for a Neutrik RCA, 3D printed an insert to adapt it for a 4mm Banana Jack. I'll be mounting it inline, to the right of the existing RCAs.

I am having a balance issue with my arm. My right channel is noticeably more quiet. It is definitely in the wiring in the arm. I have swapped RCAs left to right, and even cartridge leads. It always follows the right arm leads. The arm ground is tied into the right channel ground. I am wondering if that may be the reason. Or I have an internal arm loom issue.

I am starting by taking the ground off the right channel, and making a separate path to the amp.

I modified a Neutrik RCA socket to take a single banana jack (3D printed some bushings). And installed the separate ground. I hope to test tonight.

Have you checked the cartridge clips? Not all cartridge pins are the same diameter, and the clips should be tight.

Cheers,
Alec

Probably what you suspect (The arm ground is tied into the right channel ground. I am wondering if that may be the reason.) although I have no idea why...

Or - could it be the cartridge ?

If you have a separate ground lead then you should probably remove the link that ties the right channel signal return to turntable ground. Ground the tonearm (if possible), the subchassis, and the chassis, all to a single point that goes to the dedicated ground wire, but keep both signal returns separate from the ground.

My issue persisted even after separating the ground from the right channel.

I noticed that the amount of hum I had changed as I moved the tone arm left to right. Not gradually, but almost in steps or pops. I found that some enamel had been scraped off of the Van Den Hul lead wire, causing an intermittent short inside the arm.

My solution was to rewire the arm with Cardas Clear (Silk) 34awg tone arm wire. Re using one of the Van Dan Hul wires as a ground. The wires are continuous from the cartridge clips to the RCA jacks. I 3D printed a tapered bushing for the bottom of the tone arm, so the wires no longer brush against metal where the arm moves.

My hum and balance issue is now completely gone.

While I was pondering my balance issue, I also came up with an idea for changing my anti skate slightly. Instead of the loop on the wire for the anti skate weight. I am now using a YoYoFactory Center Trac grooved high speed bearing. Not for the speed obviously, but for the smoothness. This is supported by a new 14awg copper wire arm. I get the placebo effect all too well. But I do think its made a difference.

and just a nice pucture I took before the bearing upgrade. cause im a picture whore. lol
