TT set up question

Inner groove distortion can be caused by misalignment of the cartridge or incorrect anti-skating. The alignment and overhang settings should be checked with an appropriate guage that is usually supplied with the tonearm. If you notice that the distortion is mostly in one channel, then it's usually the anti-skate setting. Distortion in the left channel (the inner groove wall) requires a decrease in anti-skate force, while distortion in the right channel requires an increase in the setting. The proper anti-skate setting should allow the cartridge to ride more centered in the groove, with equal force and tracking ability for both channels. Good luck, and let us know what you find.

I haven't had a table for a while, but how do I know if his antiskating is set right? Which way should the arm deflect when it's raised from the LP?

Observing which direction an arm deflects during cueing does not tell you how to adjust antiskating. That idea is absurd.

One problem at a time. You haven't answered Seandtaylor99's question, which was important and well chosen. Identifying your friend's problem depends on the answer.

I have used the Wally Skater in the past to set my anti-skate on my Kuzma Stogi tonearm. I found it interesting that the factory recommended setting based on my cartridge VTF and the Wally results were different, by quite a bit. I confirmed the Wally anti-skate results with a test record.

Nsgarch has posted an interesting method for testing anti-skate. It is is the opposite of what you mentioned. Instead of deflection of the tonearm on the rise, look at what happens to the stylus when you lower it onto a spinning record. If you don't have the anti-skate set correctly you will notice a deflection one way of the other. Good light and perhaps a magnifying glass help with this test.

It wasn't end of the side distortion, if it were, I would have responded to the question. There was probably a couple of minutes left on each LP every time it happened. The sound was similar to an electrical discharge.

Doug, sorry for being too stupid to know that my idea was absurd! If only I knew as much as you...

Clio, that's some good advice, I will check it next time I'm there, or just pass the info along.
