On my Hickok TV-7 tester they read 74 and 78. A reading of 43 would represent the minimum recommended value. These lightly used General Electric tubes are from USA production. The 7B7 is a remote-cutoff pentode with Loktal basing. This tube type is used for RF and IF amplification in vintage radio circuits. The 7B7 is a somewhat scarce tube type today. This tube type was widely used by such radio companies as Philco, Silvertone and Zenith.
