Phoenix Eagle causes vibration w/ 300 RPM motor

what's interesting to me is how much quieter a properly running Lenco motor is than the Hurst.

VPI solves the vibration problem by not allowing the motor pod to touch the plinth, anywhere.

One of the reasons the SAMA made such a difference in my old HW 19 3/4.

The "custom" plinth I have (a Radgear) has the motor pod sitting on the bottom plate of the plinth....any vibration from the motor goes straight to the bearing and even the tonearm.

A simple solution is to correct this design error....cut the plinth and have the motor pod a stand-alone.

But there may well be something in the circuitry of the Eagle that causes the Hurst to vibrate more.

Its all very interesting.

Sorry to be late here. But to answer your original question, I use an Eagle/RR with a 300 RPM motor and it is vibration free and dead silent.
