Sensibly equivalent¶ to:
The 6BZ6 is described as a semi-remote cut off pentode (Variable μ) for use in television receivers within the IF strip. Thus it was designed to provide wideband amplification at 30 - 40 MHz.
The mid section of the envelope is coated to minimise the release of gas from the glass caused by electron bombardment. This happens as the anode does not enclose the cathode but exists as a couple of plates facing the main electron flow.
Below the opaque band on the envelope one can see the central cathode/inner grid assembly in the centre with beam plates as bright metal and the outer curved anode plates.
The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins is 48 mm tall.
Reference: Data-sheet. Type 6BZ6 was first introduced in 1955. See also 1955 adverts.
