Doug's right; it seems like a pickle. The Shure is very high compliance, so that can probably be eliminated. Is it possible to use headphones to see if it is an acoustic feedback issue? The bass frequency makes it suspect for that. You might also put a small mirror on the turntable mat, without a record and lower the cartridge onto it with the anti-skate completely off. This will magnify any problems with azimuth, perfect tangency to the record. Sometimes, if the stylus does not meet the record squarely, these problems can come up.
New cartridge, now some adjustment questions.
I recently purchased a Shure v15mxr cartridge on closeout and mated it to my music hall mmf-2.1 table. There has certainly been an enormous improvement in sound quality. Just this week my back-ordered Hi-Fi News test record came in, and after running its tests, I can hear that my cartridge is not tracking all the test tracks perfectly. So I have a few questions.
1) It has some difficulty tracking the 300hz test tone tracks on side 2. On all three tracks there is at least slight distortion at some point in the track. I tried re-aligning my cartridge, but got no signifigant change. What factor is typically at fault here? Is it cartridge adjustment, or some other factor?
2) On the bias setting (anti-skate) tracks, it tracks the first two perfectly, but starts to break up slightly on 3, and terribly on 4. My table has limited anti-skate adjustment, (weight on a string). I made it better with some adjustment, but given that these are also 300hz test tones (as the tests above), I assume the two are related.
This seems to be a very helpful record, except they don't give many suggestions as to fixing the problems you find! Suggestions would be much appreciated!
