Description: Quantity ONE(1) - Dated 1994 Pavene 811 Power TRIODE Tube Calibrated TV7D/U tested 11.3mA Plate Current emissions(@150VDC Plate Supply) Gm= 44.0/(36=min good), 44 = 1,100 uMhos Transconductance(Gm) Etched in Glass : "94 03", 'P' with a '-' dash on top of the P inside of a circle, then below is etched"T-811" .-White base,- believed to be made in PRC - China Our test bench: Recent Dan Nelson calibrated (07/24/2023), restored and upgraded TV7 with Digital Meter reading Transconductance in uMhos (Gm) and mA (Anode Plate Current). Calibration re-verified 01/06/2024. Ships in Plain white box. We will include a printed page of this description in the box shipped which will include all test results.. Condition: OPENED the BOXES to RE-TEST them on a Dan Nelson Rebuilt, Upgraded & Calibrated (07/24/2023) with Digital meter. Both tested against RCA Factory Data Sheet Specs and Strong for Transconductance (Gm) & mA (Anode Plate Current Dissipation)given this tube was tested at only Plate Supply Voltage of 150VDC. ** Please see ALL PICS for test results and the RCA (HB3) 1963 Factory Data Sheet Specs. Preview the Graphs to see the Gm and mA results given these tubes were test at only 150VDC Plate supply voltage **** Note: All Versions of TV7's test at a Maximum of 150VDC Plate Supply Voltage and 135VDC maximum Grid Voltage and 0V to -40V Control Grid (Bias setting) Volts.
