Brimar 1948 2102 battery double-diode triode, triode section. Typical anode voltage 135 V, plate current 2.1 mA, grid bias -1.5 V, plate resistance 23000 Ω, gm 1.3 mA/V = 0.0013 A/V, amplification factor 30. The 135 V value is typical operating voltage and NOT maximum plate voltage, so max_plate_voltage remains null. Directly heated 2 V 0.12 A filament shared with both diodes, U.X. six-pin base.
