IV-1 help needed

[Dylan Distasio]

Hi folks-

Hoping I can get some assistance with driving an IV-1 VFD (dot dash) tube.  I have still not gotten around to building VFD circuits on my own from scratch (I've built a few kits), so do not have a great handle on this.  I've tried to muddle through the Russian datasheet but have not fully translated it.

I figure someone here must be familiar with these for separators in VFD clocks.

Let me start with pinouts.  If I am reading the datasheet correctly, I believe:

Pins 1,8 are the filament

Pins 2,3,4,5,6,9,11,12,14 are not connected.  Does this mean they are literally not connected, and are just there for physical support or can be clipped?  

Pin 7 is the grid

Pin 10 is the dash (anode)

Pin 13 is the dot (anode)

Assuming I have gotten this far without an error, can someone confirm these voltages?  I may be really off on what I am assuming is what, since I have not fully translated this.

Pin 1- 0V (ground)

Pin 8- 0.85V

Pin 7 - 20V

Pins 10,13 20V

I am unsure how to read the current limits on the datasheet.

Apologies in advance on any ignorance or mistakes, and thanks for any help.

Best,
Dylan

Yup, that should light it right up. You can use a pair of 9V batteries for the grid/anode supply for testing.

Yes, IV-1 is designed to display information in the form of dots and dashes. Therefore, only 1,8,7,10,13 Pin is used. By the way, I have a IV-1. Does anyone need?
