The EF80 internally screened pentode was a workhorse of the VHF TV receiver and was introduced in 1950. It was described by Mullard as: a high slope RF pentode and not a variable μ type. The EF85 was the variable μ counterpart to the EF80. The EF80 was much used for RF, intermediate frequency, and video amplification.
