One(1) TV7D/U RE_TESTED at Factory Gm&mA 1962 RCA USN 'JAN' CRC 6159 VHF Beam Power Tube. - Glass etched 'ODA' under RCA Octangle Stop Sign with 6159 etched inside. - Metal base inked '62 04' production - No box available, well pack very well for extra safe shipping - The 6159 vacuum tube is a 26.5v filament version of the popular more common 6146/A/B Power Output tube - Filament/Heater Vf: 26.5v (+/- 10%) If: 0.3 Ampere Condition: Plug-In and Tx, Clean Glass, Pins, Top Cap and Locator. Found out of Box in Large Military Surplus Lot - TV7D/U Re-Tested at Factory Data Sheet 'Bogey' Gm &mA Emissions Test results listed and in pics . TV7 Settings : 6159 25.0V HS5-0318 Bias=30 - Selector=D GmButton=3 MinGood=35 Cap connects to plate. Minimum good on a TV7 reads 35 = 4,375 uMhos Transconductance(Gm) RCA factory 'Bogey' when tested at 200VDC Plate Supply, 200VDC Grid#2 = 7,000 uMhos(Gm) at 100.0 mA Plate Supply (+/-10% variance). (Please note all TV7 versions test at max 150VDC Plate Supply, 130VDC Grid#2 and 0 to -30V Control Grid#1(Bias) ). Test Results: No Shorts, No Leakage, No Gas, No Apparent Microphonics Tube 1: 'USN' 'RCA CRC - 6159' Glass etched 'ODA' '62-04' 55.7/35 = 6,962.5 uMhos(Gm) at 95.7 mA 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.
