The S6F33 is a special quality version of the 6F33 RF pentode, the structure is open with the anode being formed by two small plates that are strapped together. The suppressor grid is closely spaced and the valve has a very short suppressor grid control curve.

The thin glass tube envelope is 18 mm in diameter, and excluding the base pins is 44 mm tall.
