It's quite close to the Eimac 3-1000 except for the lousy amplification
factor which will be a handicap from the drive requirements standpoint. The
-1000v is nothing just a design limit; in normal operation it will probably
require something around -50 t -100v V bias at a plate voltage of about 2500
V and proportionately higher with increasing anode voltage.
Use it only if you have no other choice.

      Good Day,
  Well its been awhile since I posted to this list but read the posts.  My
weakness is how to determne if this tube is suitable for use as a ssb amp
and does anyone have a tutorial or link on how to use the constant current
characteristic tube charts? That -1000v grid in the specs makes me think it
wont work or be practical but thats why Im asking.
