    New in Box, Vintage Raytheon  5Y3GT VT-197A Vacuum Tube
    Tested Good on Hickok 539C tester
    (54 is minimum good reading)
    Results:  82/103  = 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
    Results: 69.1 VDC / 68.5 VDC
    GOOD
    (normal range  68.1 to 70.0VDC higher is better)
    Long-life test results:
    Good    76/68 at 4.3VAC on filament     68/78 at 3.0VAC on filament
    Your tube will be shipped to you by USPS First Class
    within 5 business days - usually MUCH FASTER!
    Thank you.
