VPI-HW19 first model

Just got this turntable out of estate sales. Has original Sumiko MMT arm on.

The owner stated he changed motor 2 years ago and it's Hurst 600rpm motor.

My issue there: This motor is LOUD and it's clearly heard through the record surface. This motor seems to be a stepped synchronous motor. I tried to damp this motor mount bracket with silicone gasket and it still transfers too much vibrations onto the platter and arm boards.  The original owner also supplied me with original motor that is still functional.

Tried to contact VPI -- no luck/no response after numerous e-mails (are they still around or gone?)

Tried to contact Hurst -- no working phone or e-mail listed on their site.

VPI is still around but more than half their staff has Covid.  If you have a Facebook account, you can contact Matt through their FB page.

Does it have a spring suspension or sorbothane suspension?

A common problem with the early HW19 motors which were not rigidly mounted like everyone else was doing at the time and VPI changed to.

VPI should be able to provide you with a replacement 600 rpm motor capacitor that should greatly reduce motor vibration. I’ve successfully used their 0.47pfd 600VDC snubber capacitor although it is optimal for the 300 rpm Hurst motors.

Rigidly mounting the motor on a proper absorptive metal piece to further sink noise as well as heat would be much preferred. The optional VPI SAMA - stand alone motor accessory was (is?) specifically designed for this purpose.

I’ve rebuilt a number of those Hurst motors which is fairly easy to do if you have access to VPI’s locking (set-screw) output shaft collars 👍
