Brimar 1LA6E directly heated 1.4 V 50 mA battery heptode frequency converter with eight-pin loctal base for superheterodyne oscillator/mixer service. Brimar explicitly directs the reader to type 1A7G for further operating characteristics and curves; quantitative values from 1A7G were not independently established as identical maximum ratings for 1LA6E and therefore remain unpromoted. One physical heptode, published conversion application and capacitances.
