Title: Globe King Modulator Post by: W8UJX on February 17, 2009, 11:06:02 PM I have a question about the modulator used in the WRL Globe King transmitter.
I remember seeing an article on a website concerning the addition of negative feedback around the 6L6. If I remember correctly it involved the addition of a resistive divider across the primary of the 811 driver transformer. From the center of this divider the signal was connected to the plate of the 6C5 through a 100K resistor. Does anyone have any information concerning this mod or know where I can find the website? Tnx, Jerry, W8UJX jk.ashley@earthlink.net Title: Re: Globe King Modulator Post by: Steve - WB3HUZ on February 18, 2009, 08:46:59 AM If you can find a Handbook from the 50s or 60s, the info will probably be in there.

I have a modified GK400B and an unmodified 400C. The modulator decks are significantly different. The Couplates on the 400B have been removed.
