DP-59L ringing noise from motor

Post by lorr0210 » 11 Aug 2017 23:50

When I start the TT I can hear a ringing/humming noise. However, not audible through the speakers once music is playing. Pretty sure it's the motor, but just wondering if it should be silent, or loud enough for me to hear?

Thanks in advance.

Be sure the magnetic pickup hear is not dragging on the inside of the platter outer ring. this can make the TT inoperable.

Yep, I've a feeler gauge set and it's set to spec, so that's not the issue. The sound is coming from u8nder the TT/plinth.

I had a problem with the way the transformer was hung on a plate with washers, and originally I thought it was a bad main bearing. I cut some thin rubber sheet to put between the two surfaces, and now it is dead quiet. I can't think of anything else.

Hello,

I know its been a while since this question was posted, but I hope it is still possible to get more information. I have the same Denon TT and I have recently noticed identical problem.

The motor rings only when starting and stopping, or when I hard press the brush when cleaning dust from records. Otherwise it is dead quiet. If I turn the plate by hand, it is also dead quiet.

I suppose it has something to do with the motor, because the noise is only present when motor needs to engage with high torque. Maybe electronic control is also an issue. Or maybe the whole thing is just normal?

Did anyone else notice this, and did you find out what was the problem and a solution? Thank you!

Have the transport screws been removed?
