Reproduco Piano-organ Power Consumption
By Allan Rustad

>  starting current: 25 amperes peak
>  running current:  8.8 to 8.9 amperes

[The observed] starting current is quite high for a typical residential
system.  It would be a good idea to start the two motors sequentially,
rather than simultaneously.  A simple time delay relay in the starting
circuit would do the job, or a pressure switch on the pressure or
vacuum pump could start the second motor.

Allan Rustad

 [ The typical Reproduco has a separate power switch for each motor,
 [ mounted at the right side of the console, but Ray's is not typical.
 [ Long ago the blower and vacuum pump were placed in a large housing
 [ for remote installation at a mortuary, with a big DPST relay for
 [ remote power control.  Ray is installing an "industrial" power
 [ circuit suitable for the application.  (It's much the same as the
 [ electric wiring at motels that powers the large air conditioning
 [ unit inserted in the wall below the window.)  -- Robbie
