All -

I've acquired a 28KSR that contains a WesternUnion interface instead of the
normal LESU. I cannot find a part number on it. This interface has 1/4 (or
telco) jacks, and an empty relay socket labelled "Relay Subbase 202-A". I
don't know if it needs the relay. The interface contains a large Cinch
connector that goes to the stunt box, but I have not researched which
functions are performed by it. Also, the terminal board on the KSR base has
cut pigtails leading to the AC motor terminals, but the rest of the base
seems to be wired ok. Turning the power switch on does nothing.

Anyone got a schematic, or at least a good description of how this interface
works? Or, if anyone has a spare genuine LESU that can replace it, I'd be
interested...

Thanks
