RE: hum related or bearing noise?

The before and after needle drop results without the platter spinning were identical. Without the Falcon shows the same spike at 120 hz.

I have the motor sitting on a mouse pad and four Herbies Tenderfeet. Must not be enough. The table feet sit on 4 Herbies Fat Grounding Bases, all of which sits on 2 inches of maple and 4 Mapleshade Isoblocks. Is it transmitted through the belt or where is the weak link?

Since everything I record goes through iZotope RX 4, I am filtering out the 120 hz (and 60 hz) noise, but it probably takes out anything else at 120 hz. I'd rather fix this.

Is motor bad or not properly isolated?

The 120 hz noise is the most audible.
