I can remember seeing at least one project for a crystal-controlled
timing source using tubes (I think it used push-pull 6F6's in the
output stage) to run an ordinary synchronous-motor wall clock. This
would probably be during the 1940s or 50s.
Does anyone remember that the oldest of said wall clocks required the
owner to start the motor manually by spinning a little knurled shaft
located on the back?
I seem to recall a rumor where the power companies were offering to replace at
no charge those clocks that needed to be mamually started (before my time.) The
reason had something to do with using power that didn't register on the power
meter. Anyone here know if this is fact or fiction?
