Re: [TCML] Unexpected RSG phase shifter behavior



I don't know how well it would work with the phase controller.
In any case the poster said he mis-wrote and actually
has 2 flats on the 3600 rpm motor.

Live and learn! Wondering if it has any effect when using a phase 
controller - I'm wondering if it's still possible to get up to 90 
degrees of shift still, if not that could have been the OP's original 
problem of not noticing a difference?
