Notes
10V heater variant of the 7AD7, designed for series-string heater circuits in television receivers. Same electrical characteristics as the 7AD7: gm=9500 umhos, rp=300k ohms at Va=300V, Vg2=150V. GE Essential Characteristics lists this type with the same operating data as 7AD7. Very rare type — limited production for specific television receiver designs. Pin Layout — Loctal
