My Handbook has data for the 4-1000 as follows:
Telegraphy - 3,000v plate, 500v screen, -200 grid, 700 ma plate, 146 ma
screen, 38 ma grid current
AB2 - 4000 plate, 500v screen, -60 grid, 300/1200 ma plate, 0-95 ma screen,
11 watts driving power, 3 KW out
That may be a bit more than the G license allows. I have some 4PR1000 tubes
and interchange them with my 4-1000 tubes and assume the current is the
same.
