Mazda/Ediswan 6F1 high-slope screened RF pentode with eight-pin B8A-style rimlock base and 6.3 V 0.35 A parallel heater. Manufacturer maximum plate 250 V, screen 250 V, plate dissipation 3.5 W, screen dissipation 1 W (with appropriate grid-cathode resistance condition); typical Va=Vg2=200 V, Vg1 about -1.8 V, anode current 10 mA, screen 2.6 mA, gm 9.0 mA/V (0.009 S). Manufacturer electrode capacitances plate-to-earth, control-grid-to-earth and plate-to-grid published with/without holder and shielding; flag true. Manufacturer descriptions distinguish RF/video output service and limits at alternate operation.
