Maybe more luck here, at lp140xp problem

Post by caius_1987 » 13 Jan 2020 22:32

When the speed is quartz locked if I put the antistatic brush on the record it sometimes moves to a higher speed (+3,3%) after being previously locked on the correct one. It maintains the new speed unless I stop and start it again. Am I missing something? :?:

It's apparently trying to compensate for the drag of the brush, but it's overcompensating. Since it doesn't come back to normal speed when you lift the brush, I'd call it a defect. I'd contact Audio-Technica, and hope it's a warranty issue. Even if not, I want it repaired.

I agree with the exception that if it is out of warranty, I'd just put up with it. Having an AT LP120 USB myself, and using older DD's that don't have a "quarts lock button", I'd have no problem with just moving the slider to where it needs to be. Yeah, it's a workaround, but I would see it as one of the least impactive workarounds known to man. :D

The thing is this model has a different strobe than others I’ve seen: whatever speed the dot line used is the same. It is marked 0 and has large dots

Applying a carbon fiber anti-static brush typically slows my AT-LP140XP only briefly, if at all. Testing just now and pressing hard enough to slow it, then speed recovers quickly after brush removal, whether or not slider is set to 0, if quartz lock is set prior to brush application.

Conclusion: one of our two AT-LP140XPs is exceptional.

Are you using the Felt mat? I took it off and it seems not to do it anymore. Recovers really quick now
