Radiotron UX201-A used radio tube made by RCA

Description

Radiotron UX201-A radio tube. The condition is "Used" and appears the tube itself is in good condition. The tube has not been tested and I can not guarantee that it will work. The tube has been sitting in my closet for over 40 years after I had inherited it from my grandfather who was an amateur radio ham. According to the sticker shown in the picture, the tube appears to have been tested by my grandfather on April 10, 1929 so it is at least 92 years old. The tube has been stored in the RCA box for an UX-112-A along with the original specifications page and these items will be included in the sale even though they don't really belong to the tube I am selling.
