[Boatanchors] Need Globe King 500C Modulator Question

[Gary H. Harmon, Jr.]

>From my friend Ron......

 

I had an epiphany on the control circuitry of the GK "B" modulator and now
know how to do it.  Took a while, brain fog!  All I need to figure out is
how WRL made the spark gap device across the secondary of the modulation
transformer on the "C" modulator and also the value and wattage of the load
resistor they installed across the secondary.  Have you ever seen this
device and resistor?  No pictures in the manual and no references in the
parts list for either.  It just shows up in the "C" schematic.  

 

Anyone know the answers?

 

Thanks and 73,
