Thanks for the advice but I have about ten more spare SA-851s,
five or six 850s, five or six 801s and a dozen or so Seimens.
I was actually looking for someone who might be in need of
50Hz operation.  Is there anyplace in North America that runs
50Hz?

BTW, it's actually the motor side pulley that is different.
The flywheel seems to be the same size.
