Platter off motor noise. Should it put me off?

Post by MichaelDaran » 21 Aug 2017 09:14

Hi. Thinking about purchasing a Pt1. Owner says that the motor run's smoothly when the platter is on but a little noisily with platter off. Should this ring alarm bells? He also says that some carts can pick up noise from the transformer and that he has put a shielding plate under the top plate. Please advise. Thanks Mike

Only the very earliest PT1 had a transformer under the switch in the front corner, later units had a wallwart adapter and just provided DC direct to the deck. You are looking at a turntable that was probably built in 1981, the motor could easily be worn by now the only way to tell would be to see / hear the deck. Buying from a long distance ? Look at the possibility you may need to buy one of the many modifications that replace the early motor.

Motor noise is quite usual, as the DC motors spin at a few thousand rpm, whereas AC motors are around 250rpm... the noise vanishes behind the music, and does not translate to noise at the needle - belt drive helps here.
