Thanks for the response, David. It's the Series 5 arm.

I've since removed the Benz and replaced it with another cartridge. I'm going to try mounting it again this evening - only this time with more mass and a higher VTF. I will take the photos you've requested and post if I have more trouble.

What I can tell you about the setup on Friday...

(VTA such that the cartridge top is parallel to playing surface for all)

First:
2g shim, heavy counterweight, 1.3g VTF (accidentally), max antiskate (quadrant on the screw hole further from the pivot, and quadrant turned to provide the longest moment-arm with the cartridge at the inner groove).

Crazy groove jumping across an entire song.

Second:
Adjusted VTF to 2.2g.
No crazy jumping, but still distortion in right channel and skipping forwards a groove or two. Removing the anti-skate made it worse.

Third:
Removed 2g shim, added 7g shim, lighter counterweight (couldn't achieve correct VTF with heavy weight), 2.2g VTF, calibrated the AS but still had to keep it at max.
Settled down, but still had right channel distortion and an odd skip.

Fourth:
Put the Ruby away.

The odd thing is that a vintage RCA of The Four Seasons tracked perfectly - the whole record, as did a 1980s Ladysmith Black Mambazo LP. They both played without any detectable distortion or skipping.

What's also bizarre is that te owner of the cart has used it on a Reed (15g) and a Breuer (8g?) at 2.5g VTF with no issues.
