The DL69 is a subminiature output pentode suitable for battery operation with an HT supply of 90 Volts. This is the Mullard description of this audio beam tetrode.
The beam plates and the rectangular hole in them is easily seen as is the single hairpin filament.
The output power at 10% distortion is between 25 and 50 mW. The connections are taken looking at the base with the red dot on the left.
The oval miniature glass envelope is 5 x 9 mm in plan, and excluding the lead-out wires is 37 mm tall.
