This tube is a conventional type 51 with a metal coating on the glass envelope, presumably for shielding purposes. Not grounded so not effective as such. Heater: 2.5 volts at 1.75 amperes, 180 volts on the plate, 90 volts on the screen, and a 3 volt negative control grid bias.” See also: https://www.radiomuseum.org/tubes/tube_g-51-s.html.
