@Bill van Dijk It's 1x6 multiplexing actually. Posted schematic is not
mine, I used it just as reference. It seems someone mixed tube connections
as well. I tried adding resistors before, but without success.
@gregebert I am not using PWM yet, but I am planning to do so, to make

The same was true about black and white crt's, all were round for quite
some time. IIRC the first 21" round color crt was a 21AXP22? Ira.

I have a couple of "out of date" phones lying around and wouldn't feel bad

But 30 years from now people probably will look at it
After watching that video, I feel more guilt about how I loved to throw

An electron cannon emits electrons in a very narrow straight beam, which is

of the tube. If you create a deflection circuitry with a deflection equal in
all directions, you get a circle. Hence the round screen. In ord
Nice video.
I have a couple of chart recorders like the ones used there while
checking the metal strips.

When Color TV's first came on the market in the early 50's all of them had
round CRT's. The first ones were 15" CRT's. Around 1954 RCA introduced a
21" round CRT and they were the standard until around 1963 when the first
rectangular CRTS entered the market. I suspect this film was made during
After watching the latest Fran Blanche video on YouTube

I started thinking about this subject.
Some Nixie tubes clearly have a getter while many don't (or at least not
visible).
What's up with this? Do lots of Nixie tubes have "hidden" getters inside?
Da
Yes you're right.
At the end of the documentary at 19:15 you can see a man testing a TV with
a round tube.

Enjoyed watching that, thanks for sharing.
Any idea what the large round tubes were used for back then?

It looks like you are using PWM dimming. Can you disable it for now, and
then focus on optimizing dead-time between cathodes and the anode timing.
I'm fairly certain you want to turn OFF the anode before changing the
cathode signals, allowing some dead-time, then turning on the next anode. I
