DL22N
 
I have a bunch of those. They can come from some swedish military supply. I've read thar they were used in torpedo control systems:eek:

Anybody knows anything about them, if they can be used in audio, linearity etc? All I can find is this DL 22N, Tube DL22N; Röhre DL 22N ID33454, Vacuum Pentode and no datasheet.

Best regards
Staffan

Some basic info here Electron Tubes & Valves Database - Index - Cross Reference under DL22. The DL22N has metal envelope instead of glass.

Thanks. Well it seems like a low voltage direct heated pentode for battery driven amplification, so the torpedo rumour might be correct.

Eventually I could curve trace it manually. Anyone knows a thread about doing that?

Best regards
