[Drake] T-4X info

[telegrapher at att.net]

I recently came to be the owner of a T-4X.  Really nice and looks like the finals are good also.  No documentation.  I have the CD which covers the -C- Line but nothing in there that i swa says anything about the T-4X or B line.

There are two controls on the right side of the transmitter.  I don't remember just what they are but one of them affects the keying of the transmitter.  VOX gain or something.  What happens is that when i depress the key, all i get is just a slight kick of plate current.  I'm suspecting that one of those two controls needs to be adjusted, but which one?

Idle Ip is good and it loads up to full output.  Can't ask for better than that except to fix the keying.  Anyone with a manual for the T-4X or T-4XB as i think they are pretty similar.  And, what is the tube that works in that circuit.  Seems it was an odd number type?
