The 6EW6 is a straight pentode with a high mutual conductance. Although not of the vari-μ type it was designed for IF amplifier service in TV receivers.
The RCA name.
It is called a pentode but the presence of beam forming plates indicates that the construction is as a beam tetrode. The cathode is rectangular and the grids pass flat across the cathode face.
Here the beam plate shape is more easily seen.
The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 47 mm tall.
Reference: Data-sheet. Type 6EW6 was first introduced in 1959. See also1959 adverts.
