I suspect there are more than just diodes in that potted block. If I had designed this display, I would have put an inductor in series with each segment. Since the current through an inductor cannot change instantaneously, this would lessen the shock to the filament, and would help to make them last longer. But this is only speculation on my part.

Dave CAD is not painted or made to scale. :-)

FranCad is full of bugs and generally unreliable.

I had to re-upload with a correction, so you might want to repost comments on YouTube.

Love it. Do you think multiplexing or PWM of nixies would cause audible interference if installed as a display in an audio preamplifier chassis?

The more I see this board being demonstrated the more I want to see.

Beautiful. Quite a soothing glow. Interesting to learn why they chose to use more expensive parts.
