Today I got this reply from Mike at VPI:
"The 300 RPM motor does not work on the HW-19 so that is not an issue. The 600 RPm motor should work perfectly when you get the capacitor right for your countries voltage and frequency, it is a critical item and if you are willing to play with different values you can fine tune the motor for lowest noise and running smoothness. Mike"
No use running after a 300 rpm motor, then. Capacitors, here we come. Has anyone tried?
Storyboy, this sounds very interesting, can you explain a bit more ("in front of the pulley and tensions the belt around the pulley 180 degrees")?
Amazing what one can achieve with further improvements like these...
