The 6BX6 also known as the EF80 is an internally screened pentode and was a workhorse of the VHF TV receiver. The type was introduced in 1950. Much used for RF, intermediate frequency, and video amplification.
The circuit designer is given maximum flexibility by having all electrodes brought to external pins. Many pentodes have g3, the suppressor grid, internally connected to the cathode.
The thin glass tube envelope is 20 mm diameter and excluding the B9A base pins stands 58 mm high.
