Hi everybody. I just recently became the proud owner of a Simplex Master clock, Type 25, serial number S-1899FG. Pictures can be found at: http://staarage.ubishops.ca/Simplex I got a good deal on it because the owner who acquired it, who used to fix mechanical clocks for a living, wasn't sure that the electrical portion of the clock worked, and didn't want to risk burning anything out testing it. As you can see by one of the photos, a pair of feed wires had been cut when it was taken out of service. After manually winding it a bit, and a few probes of my multimeter, I connected a new cord and plug to the two terminals, and the clock worked great. Further investigation revealed that someone must have been annoyed at hearing the correction impulses sent out at the 59 minute mark every hour, but re-adjusting the 2 second contacts and the clock now pulses correctly at the right time at the 59th minute. Now I'd like to figure out how to wire up some slaves clocks to it, but it doesn't appear that this clock supports 24 volt slaves. Can someone here confirm this, and let me know what the correct way to wire up slaves to this clock would be? Would I need to find/build a relay cabinet in order to use 24 volt slaves, using the AC lines on the clock to keep it wound, and a separate 24 volt power supply in the relay cabinet to pulse the slaves? Many thanks in advance for any help or information about this particular clock you can provide me.
