Noise out of speaker from turntable


looking for some leads on potential issue from my turntable

have had this issue for years, in two different homes, have tried cheating the ground pin, different grounding, latest PS Audio HumBuster.

it does seem to be a ground hum, but a low level slightly fluctuating sound, which when platter is spinning, and no music, can be heard. Most of the time, when record is playing, aside from very high volume, the music drowns out the noise.

Years ago, maybe 15 years ago, when I owned a JA Michell Gyrodec, and had a similar noise, he knew exactly what it was, and replaced I capacitor in the motor i believe?

My current table has a separate power supply,it is a Symphonic Line RG-6, the rest is a Graham 2.2 arm, with a VDH Black Beauty Special X, LOMC.

i am now far away from a tech, so would like to diagnose anything here first and hope anyone can offer some advice.

TIA

Cue the arm up and while the platter is spinning and gain up enough to hear. Gently blow on the arm to transit it over the platter. Does the noise change? If so, you may have an intermittent ground fault inside the arm. If the noise is stable, repeat the test with the platter off. Does the noise disappear? If so, you may have component in the motor going bad or some kind of short between the motor and the arm ground.

Good luck!
