Of interest:  The Ampichron clock was a very well built mechanism and
contains a Telechron clock powered by a General Electric motor.

Another feature I forgot to mention was a provision for the Ampichron
mechanism to turn on a radio.  I assume there was a separate plug under
the piano for a radio power cord connection.  An additional setting on
the Ampichron clock was labeled "Capehart", a well-known radio and
record player manufacturer of the era.  I never understood why it was
not labeled "Radio".
