Gema TS41 triode

TS41 size The valve measures 105x60mm, plus a further 22mm for the grid connector. It has 3 screw connections on the base, two for the filament and the third connects to the metal skirt. The grid connects at the side and the anode at the top. It weighs around 300g.

Markings on the glass are:

Developed from the TS4, the TS41 was used in numerous transmitter applications. With six TS41s in parallel push-pull and anode modulated, pulse powers in excess of 1MW were possible.
