This twin flash tube is unusual in that it is fitted on a B14A base that is more usually seen on image orthicon camera tubes. So far we have found no operating details. The design looks to be like a modern studio flash rather than an ultra short duration flash.![](../pics/acf0166a.jpg)
The trigger electrodes are not joined together, so the tubes can be operated independently.![](../pics/acf0166b.jpg)
The trigger wires and strips on the outside of the glass. A trigger voltage of around 10 kV would be needed to start the main discharge.![](../pics/acf0166c.jpg)
The B14A base.The envelope is mm in diameter and, excluding the base pins, is mm tall.Reference: Observation. |
