    Description

    1957 Tung-Sol 12AX7 Vacuum Tube Branded Thomas Organ Square Angle Getter. Condition is "Used". Shipped with USPS First Class.
    From research, this appears to be a Tung-Sol tube branded for Thomas Organs. Date is 10 of 57.
    Gain tests on both triodes on a calibrated Heathkit TT-1 Mutual Conductance tester. The results:
    Triode 1:
    1550 micromhos
    Triode 2:
    1350 micromhos
    A reading of 1600 would be NOS.
    So, one side is close to NOS @1550, and the other is strong @1350
