[Amps] motor run cap

I think I sent you a heavy current cap to be used as a feedthrough for filament voltage, didn't I?  Don't really remember.

I think that idea of getting a proper motor capacitor at a supply shop is a good one.  
Those caps cause a phase shift between windings on a motor, so one winding pushes and the other one pushes a little later.  So they need to be able to take a bit of current.  On a rotor we can probably get away with a lossy one but on a blower that thing has to work continuously, so best to get a nice modern, efficient one is my two cents.
