Sylvania 212-D

Really BIG triode. As I understand it Western Electric and Sylvania made this beastie. I have not been able to locate the datasheet but it makes a 211 look small.

  1. I knew WE made them but had no idea Sylvania did also. In fact I did not know Sylvania made transmitting tubes at all.

    The WE version was used in the superb Bell/WE pavilion display in the old Chicago Museum of Science and Industry. It was there from sometime before 1969 through the early eighties.
