    Description

    RCA Radiotron UX-280 [80] balloon rectifier.
    Late 1920's [between April 1928-March 1929]
    Tested on a Dan Nelson calibrated Hickok TV-7/U.
    Results: 46/41 [min = 40/40].
    Historically most RCA & Cunningham globe style 80 tubes function well below the 65% military recommended minimum, so this tube has many years of life left.
