Original Description:
Up for sale I have a RCA Cunningham Radiotron Type 50 USA MADE Vacuum Tube With Engraved Base. This tube is equivalent to a UX250 or CX350. This tube is a shouldered tube with black plates, and engraved base and a foil getter. Tube In very good physical condition. The base is nice and tight, The pins are tight and straight. There is no rattle nor debris in tube. Tube tests 75/60 on my HICKOK TV2-A/U military tester with 60 being the lowest acceptable by military standard. Also tes...ted 1800/1500 on the B&K owned by the estate I got the tube from. The box has tape on it and is not perfect but has done its job to protect the tube as the tube is in beautiful condition.
