Yamaha YP-B2 rumble HELP!!!!

[toad prince]

Back to vinyl to play (& record on mp3) my old LP's. I have a Yamaha CR840and a YP-B2 TT that has a mean "rumble" to it. I got it from C-list and its a low end unit I realize but the rumble can be felt on the plinth and heard in the speakers when turned up. Any help would be appreciated! Thanks...

Look for any deposits on the motor spindle and also lube the main bearing. I have one in my shop and can't say I have noticed any rumble. What does happen with this TT is the motor suspension grommets get tired and allow the motor to drop to where you can't get the speed dead on. Losening the motor spindle and raising it will fix that.
