[GreenKeys] Model 28 governed motors?

[David Ross]

greenkeyers -

  Is anyone out there using a Model 28 with a governed motor rather than
a synchronous motor?

  In the Model 15 world, a tuning fork is used to check & adjust the
speed of a governed motor -  does Model 28 equipment use this same
scheme to check governed motor speed?

  If yes, then does anyone have a Model 28 tuning fork available for
sale/trade?

thanks & 73
