    Description
    Pair (2)
    NOS/NIB
    PHILCO
    Type 35/51
    Amplifier tubes.
    TV-7 test NOS.
    Up for sale is a pair of NOS/NIB Philco type 35/51 amplifier tubes.
    The grid caps and bases are tight with no loose particles inside either tube or base.
    They were tested for transconductance (Gm), noise, gas,
    and
    shorts on my Dan Nelson calibrated TV-7/U tube tester using a digital meter for greater accuracy.
    For the type 35/51 tube to be considered "new" a TV-7/U test result of 42 (Gm=1050) is needed.  The TV-7/U minimum recommended value (65%) for the type 35/51 tube is 26 (Gm=650).
    As pictured from left to right with TV-7/U test results, Gm and relative strength compared to NOS value.
