Hello out there!
I am trying to get some tracking issues worked out with my 4002.
I have a Hi Fi News test LP. I had my original MMC600 re done but seem to be having trouble setting it up. At 1.1 grams it will not pass any of the tracking bands. At 1.5 it will pass the first band (300HZ at 12db)
I have checked balance, azimuth, parallel and stiction and all seem good. One thing I noticed is in a blank section on the LP with no groove just flat vinyl it will drift right as you are looking at it. My Dual 1229 will also do this as a result of anti skating but I can set that to 0 and it will stay where I set it down without drifting. Is there any anti skating on a 4002?
Any help will be appreciated.
Thanks, Jim.
Hello Jim,
One of all benefits to use a tangential tonearm is to not have to take care of such anti skating, the main reason of that is the tonearm is slaved by the little motor and does not have any potential out side drift.
So the best way is to check carefully if the tonearm is parallel relative to the tonearm sensor when the cartridge is cueing on the groove of a vinyl, if not you should adjust it accordingly to the service manual, that could explain the drift or a defective cartridge could also conduct to that matter.
In another words check that when all are in movement on a vinyl, not in static.
Perhaps the other way to consider is the tonearm sensor detect continuously the vinyl as it should do, but the cartridge has no groove as a guidance and conduct to a slight outside drift...who knows...
