Beschreibung

This tube was originally developed for Philco by Sylvania. A very few companies made the tube and it was made in the mid 1930's by General Electric as a replacement. It was only used in the Philco model 46 radio and was not on the market for long. The tube operated as a sharp cutoff tetrode and was used as a RF amplifier in line operated receivers. This tube had a 14 volt filament and was not interchangeable with any other tubes.
