Well, not only that but the tension produced by the belt would constrain isolation effectiveness of both platforms.

Dear Lewm, Dear Peter,
I would like to answer you but I cannot. My ideas, thoughts and experimentation results cannot be seen the way I want it.
sorry.

I did lose something it turns out. After dark when the ambient noise level was at its lowest, I could hear some rumble. It is faint; but there. So the bushings are transmitting some mechanical vibration from the chasis to the sub chassis. I have some ideas to try out. I can't go back to an unconstrained horizontal axis...

I overreacted. The last record that I played the other night must have had noisy vinyl. I listened last night and heard no rumble. I cranked up "For Duke" again. This record has dead quiet vinyl. Sounded great- saxophones and trumpets all over the room.

I think that back in the day, a few tweakers used to disable the suspension on SOTA tt's entirely and then mount them on any of many various isolation platforms. In other words, turn a suspended tt into an unsuspended one. Let the platform do the work.
