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.
