| Description |
So far we do not have complete data of this tube, but from the article of M. C. Sprinkle and the measurement of 2 new tubes we can roughly derive the following operating data:
Ua = 250 V
Ugsc = 75 V (via approx. 9 kΩ to 250 V)
Ugc = -12 V
Ia = 40 mA
Igsc = 20 mA
Gm = approx. 3500 µmhos
Operating data for 300V plate voltage to come.
