Notes
Directly heated (filament cathode) — observe heater warm-up time before applying B+.
4.0 V / 0.12 A heater — designed for European 4 V heater supply standard, not compatible with 5 V or 6.3 V American heater circuits.
Maximum DC output current depends on transformer voltage: 70 mA at 2x300 V, 60 mA at 2x400 V, 60 mA at 2x500 V.
Maximum C-input filter capacitor: 50 µF at 2x300 V and 2x400 V, 50 µF at 2x500 V.
Minimum total series resistance (Rt) per plate: 2x100 Ω at 2x300 V, 2x150 Ω at 2x400 V, 2x200 Ω at 2x500 V.
Rimlock (B8A) base has a locating key for correct insertion — 8 pins arranged in a circle with a central locating spigot.
