IN-4 (ИН-4) (Reflector/Sovtec) |
There were different shapes of this tube.
This is shape 1.
This tube can be used as a biquinary tube (cathodes connected externally)
or a normal nixie tube (anodes connected externally)
The datasheet of this tube has a mistake in it.
It reads, that only one anode should be connected. This is not correct!
Both of the anodes must be connected (Pin 10 and pin 13)!
