Default Re: Magenta Master Clock Question

Hi,
I don’t have one of these, so can’t provide any help, but ask a few questions.
I believe the movements were 20 v and wired in parallel. Whether the slaves were driven from the master clock contacts would be doubtful as they are only light. The contacts would have driven a relay, which in turn would run the slave circuit with 20v pulses. You mention the clock works on 4.5v, that sounds righty fit the pendulum drive coil, what voltage is stated on the rear of the pilot slave movement?

Are the Dictograph slaves unipolar or alternate polarity?
