They are old WW2 pentodes used as pulse modulators. They will work up to
6M. The filaments are 24V and the sockets are very hard to find. Typical
ham use ran 1500V on the anode and 350-400V on the screen.
I have not heard of them for over 30 years but I have complete specs
somewhere if others are not able to help.
