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.
