Valve Gallery - Rare And Unusual Valves (5)

Valves: AZ11, S130, Neon, Vibrator (41-3286-3E).

Shown above is a Telefunken AZ11.  Probably just pre-WWII.  German manufacturer, rectifier valve.  Valve base type not used in the U.K.  Height of 130mm. Shown above is a Cossor S.130 neon stabiliser.  First version of this very early device, using a black paper label to designate type (which somehow looks rather morbid compared to the more usual Cossor reds, blues and greens!).  Height of 130mm in balloon envelope.  B4 base.

Shown above is another stabiliser, though not marked.  Could have come from the top of a valve tester.  B4 base, height of 130mm. Vibrator to increase voltage, most usually used in car radios.  This one is U.S.A. made type 41-3286-3E.  Quite possibly Philco, who liked to use part numbers on the components and were a big manufacturer or pre-War car radio.  Height of 110mm.
