Beschreibung

This tube is shown on the www.bill01A website. It is an indirectly heated triode with a 4 pin UV base. One end of the heater is tied to the cathode, the same scheme as used by Arcturus in their 15 volt tubes. There is no type number marked on the tube so the actual designation is not known.
