EF42 – RF Pentode NOS (New Old Stock)

The EF42 is a miniature RF pentode designed for use in radio frequency and intermediate frequency amplification stages in post-war radio receivers. It features a B8A Rimlock base and an all-glass envelope, typical of the early miniature European tube designs. The EF42 was often found in AM/FM radio front ends and other high-frequency signal applications where low noise and good gain were essential.
