The 62-VP is a variable μ RF pentode for use as an RF or IF amplifier.

In the literature it states that although pins 3, 4 and 7 are internally connected together, it is recommended that the external cathode connection be made to pin 7 as this point offers the lowest connection inductance.

The all covering screen.

The locating pip moulded into the glass is required as the eight pins are equi-spaced around the pin circle on the base.

The thin glass tube envelope is 20 mm in diameter and, excluding the B8A base pins, is 53 mm tall.
