    Description

    New in Box, Vintage GE 5Y3GT Vacuum Tube
    Tested Good on Hickok 539C tester
    (54 is minimum good reading)
    Results:  98 / 104  = Good     somewhat unbalanced on HIckok tester but
    , see actual Fender amp results below.
    Additional real-world test was done under real-world power
    ( tube was powered up and measured using Fender Champ amplifier chassis
    (modified with 2.5K power load resistor on high voltage )
    to provide full current load on each side of the tube to measure
    performance.  Voltage was then measured with Fluke 189 Multimeter.
    (normal range  68.1 to 70.0VDC higher is better and matched closer is better)
    Results: 69.1 VDC / 69.7 VDC
    GOOD
    Long-life test results:  (Filament Voltage is reduced drastically to prove life/emissions)
    VERY STRONG LIFE TESTS    98/78 at 4.3VAC on filament     78/83 at 3.0VAC on filament
    This is a GREAT 5Y3GT !
    Your tube will be shipped to you by USPS First Class
    within 5 business days - usually MUCH FASTER!
    Thank you.
