EF80 – RF Pentode NOS (New Old Stock)

The EF80 is a general-purpose RF pentode introduced in the late 1940s for use in television and radio equipment. It was widely used in RF and IF amplifier stages, especially in early post-war TV sets. With its sharp cutoff characteristic and good frequency response, the EF80 became a standard component in European broadcast and communications designs. Its reliability and availability made it a favorite for many RF and video applications.
