    Description

    Two, Sylvania JAN-CHS-6B4G tubes, military issue. Black dual flat plates, reinforcing rods, green printed bases. The 6B4G tube is the octal based version of the four pin, 6A3 tube. The 6A3 tube is electrically equivalent to the 2A3 for all grid and plate characteristics, with the difference of course being the filament voltage of 6.3 V instead of 2.5 V. Outstanding sonics. Tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, excellent silvering. Tubes are matched for structure and dynamic gain- test at 3300, 3300 where pass/fail is 1900 micromho. The tubes have the same structure inside and out, having date codes of " "539" and "445", the 39th week of 1955 and the 45th week of 1954.
