VINTAGE 'MIL SPEC' VACUUM VALVE/TUBE

CV1120

 

Clearing out and I came across some vintage valves.  This valve has no makers name. It's marked CV1120 HF KB/K.

I believe it's a Half-Wave Vacuum Rectifier dating to the 1940s/50s 

It appears to be in unused and in Very Good Condition but I have no way of checking!

 

  It may be of interest to someone?

Good Luck and thanks for looking!
