Description

Car radio push-pull twin output pentode
The ELL1 was designed to achieve a comparatively high output power of 5.5 watts at low heater- and plate current, yet its quite-plate + screen current at 35 mA was much higher as with the competing twin output triode EDD11 at only 7 mA
[Jacob Roschÿ,6Apr2003]

The ELL1 also is listed in a British Tungsram leaflet of August 1938.
