[Milsurplus] 211 Tube Note

[Hue Miller]

>From RCA booklet "Radiotron UV-211" dated Jan. 1932:

"Radiotron UV-211 is not recommended for use at 
frequencies greater than 3000 kilocycles. There are 
other types of Radiotrons especially designed for use
at hgher frequencies. In any case, the radio frequency
grid and plate currents of the UV-211 Radiotron must
never exceed 7.5 amperes."

No other explanation! However, i'm sure the grid would
not stand 7.5 amps!  -Hue Miller
