Schickerling TVT 200
DC Detector

The TVT 200 was an early triangle plate tube using 5 triangles, 3 connected to the plate lead and 2 connected to the grid lead. This was a storage battery tube, recommended for use with a filament voltage of 4 to 5 volts and a plate voltage of 16 to 45. This sample is missing its paper label, similar to that used on the TVT 11A.
