Description

This tube is a specially designed 201A type with two filaments and a switch adjacent to one filament pin. If one filament burns out, the switch can be operated so as to use the second filament, thus giving the tube "double life". Alternatively with the switch on and both filaments in use at the same time, the tube operates as either a 112 or 171 power tube.
