This small double diode has an unusual base. The 'P5' side-contact base cap was, we think, a Philips special (P = Phillips?) and was also used on a few TV tubes, including the miniature MW6/2 projection tube.

Valves with side-contact base caps were widely used in Philips sets during the later 1930s but some other set manufacturers disliked them so Mullard were forced to market '-C' versions of their side-contact types.

The balloon envelope is 29 mm in diameter and, excluding the Ct5 base pins, is 86 mm tall.
