Description

Quantity Two(2) = One Pair of Vacuum Glass Tubes type 6SC7GTY, Made by TUNG-SOL in the Newark, NJ USA plant. Two(2) Mid-Late 1940's TUNG-SOL 6SC7GTY - Both tubes have identical internal construction - Dark Smoked Glass, Brown Micanol/Phenolic bases - Two Round Spiked Mica Spacer/Wafers (notes: in 1948 Tung-Sol changed to Rectangle Wafer/Spacers with Rounded Edges on tube types 6SC7GTY's, 6SL7GTs, 6DU7GTY's so this pair is pre-1948) - Two Rounded Rolled Black Plates - 6SC7GTY: Double/Twin Triode Vf: 6.3v If: 0.3 Amperes - Amplification Factor( Mu) = 70 - References from : Tung-Sol Engneering Data Sheets (ca, 1952) tube type 6SC7GTY Factory new 'Bogey' Class A1 (lowest THD) when the tube is under test at 250VDC Plate Supply Transconductance(Gm) = 1,325 uMhos at 2.0mA Plate Current Emissions Date Sheet : (change 'dot' to a period '.' in the link below ) : frank dot pocnet dot net/sheets/127/6/6SC7 dot pdf - both tubes ship in non-orginal boxes (as shown) This is the Perfect Tube type for 1950's Fender Tweed Amps (early Deluxe, Princeton), or for High-End Audio pre-Amplifiers. Tube type 6SC7GTY was built for Mobile-Avionics Military specifications Ruggedized, shock resistant, longer life, thick support rods, enforced mica spacers/wafers to withstand heavy vibrations from speakers placed close to tubes. TV7 settings: 6SC7 6.3 HY4-5062 0 - B 3 25 Triode #1. TB 11-6625-274-12/1 w/ C3 6SC7 6.3 HY3-2065 0 - B 3 25 Triode #2. TB 11-6625-274-12/1 w/ C3 TV7 Test Results: No Shorts, No Leakage, No Gas, No Microphonics Apparent ( Minimum good Transconductance(Gm) on TV7 meter reads 25 = 625 uMhos Tube 1: (Tung-Sol 6SC7GTY, Dark Brown Base with Black lettering "Tung-Sol" "Made in the USA" ) (notes: this tube is very well balanced, with life) Plate 1: 43.6/25 = 1,090.0 uMhos at 6.1mA Plate Current Emissions Plate 2: 43.7/25 = 1,092.5 uMhos at 6.2mA Plate Current Emissions Tube 2: (Tung-Sol w/ Orange ink faded overlayed on base "Made in USA" ) (notes: this tube is not well balanced however it is still strong with life) Plate 1: 46.1/25 = 1,152.5 uMhos at 6.6mA Plate Current Emissions Plate 2: 56 .1/25 = 1,402.5 uMhos at 7.5mA Plate Current Emissions Our Test Bench : TV7D/U Restored, Enhanced & Upgraded( Digital Meter and solid state bridge) Dan Nelson Calibrated( 07/24/2023). Calibration re-verified on 01/06/2024 & on 6/03/2024. Our TV7D/U reads Transconductance(Gm) on a scale of 0-120 (push button #3, for rectifiers button #7). This TV7D/U will read mA plate current emissions directly by depressing Gm button and the red button on the digital meter, We use the last published xls spreadsheet by Nolan Lee to transpose actual TV7 digital meter readings 0-120 into actual Transconductance(Gm) #'s in uMhos based upon the selector switch setting A-F. All versions of TV7's and most Hickok designed tube testers will test tubes at a maximum of 150V Plate Volts and Grid #2 at 130V volts and Control Grid #1 (Bias control) at ranges from 0 to -30Volts.
