on most tube diagrams - IC means "Internal Connection".  the pin is 
attached to some part of the structure of the tube, and is not to be 
used.  NC is no connection and the socket pin is generally permissible 
to use as a tie point or terminal.


often the IC pin is used as a structural support, but the manufacturer 
does not want to promise that it will be to the same element on future 
production.

I.C. means Internal Connection. It's usually connected to part of the tube
structure. Leave it unconnected.

[neonixie-l] Amperex 8453 Counter tube

[peter bunge]

I searched on this tube and found nothing.
Before I spend time designing a circuit to drive it, has any one already 
done so?
I don't mean the circuit in the data sheet, I mean a solid state driver for 
the ten starter pins.
Ehat does I.C. mean on pin 6? Or is it N/C as in Not Connected?
