Power - Pentode Single (NOT beam) (under 10W) ·Pentode
Power pentode designed for video-frequency amplification. Its output capability and wideband response suit television and professional video stages requiring substantially more load drive than ordinary signal pentodes.
Power pentode for video-frequency amplification. Indirectly heated Mazda/Belvu receiving tube; descriptive text translated to English from the French source.
Small-button Noval 9-contact
