2D13

 
    
Extras ▼

 

This small double diode has an unusual base. The 'P5' side-contact base cap was, we think, a Philips special (P = Philips?) and was also used on a few TV tubes, including the miniature MW6/2 projection tube.
See also 2D13 for a view of the insides.
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.
References: Data-sheet & 3002. Type 2D13 was first introduced in 1934. See also 1934 adverts.
