[WRL] Need Help From Globe King 500-C Owner

I need to build some parts to finish off a Globe King clone, and to upgrade
my 500-B to C specs.

I need values/ dimensions on the following used in the Globe King 500-C.

I want specifics taken from an actual Globe King 500-C.  I know this is a
pain...because it requires pulling the decks out of the rack.

Any help is very greatly appreciated.

These  items are shown in the  last schematic " addendum" and parts list
only by part number, so unfortunately it requires a laborious "look and
see", to duplicate them correctly.

I need to make the following :

A. SG-1  ( spark gap)  In Modulator Section:
 .... this is a resistor accross the  Millen B+ and Mod B+
connectors...paralelled by two wires with a gap of about 1/8th inch.

??  What is the value and wattage of this resistor  ??
      I seem to remember it is 5 watt carbon type.


B.  4-400 Plate Parasitic Choke... in RF deck.

    This is a resistor wrapped with many turns of wire, connected directly
to the 4-400 plate cap.

??  what is value of the resistor ??   How many turns of wire ??  what guage
wire??

I find it easiest to "measure" wire guage with some wire strippers.
the one picture I have looks like # 18..but not sure this isnt a home brew
addition.

This parasitic choke only appeared in the last versions of 500-C...possibly
only  those made by Globe Electronics.

C.

 PS-1    Screen parasitic choke  located at the screen connection of the
4-400.
usually a low value resistor inside a coil of wire.

?? May or may not be the same as the one used in the  plate of the 6146
driver ??   ( I have that here to copy)

??  What is the value of the resistor ??  How many turns of wire ?



Thanks for any help you can give.

The VRL  " Globe King 500-D" is almost up and running - after extensive
rebuild and redesign per WRL.  It is making normal power now...modulating
ok...with a bit of audio tweaking left to do...but obviously still some
unfinished details, a minor teething problems.
