Hello Michail,
I tested 4, 7 and 13 connected together as anode, it works fine.
I don't need to rise the voltage, 180V is just perfect. I'll see in a couple of
days if the 3k resistors are OK or if I must ajust
Just tie the anodes together

I made some new tests. I mounted 6 IN-12 tubes on the clock board. I
noticed that there were 3K resistors on board. So I plugged my tubes
directly into the board without adding any resistance. It worked directly
at 170V.
I am at the maximum allowed by the software: 200V
I can mesure between 195 and 198V.
At the max brightness, I am less bright than another IV-4 clock I have.
(Sputnik clock, 1 x 4 Mutiplexed + 1 OG-4)
If I enable the LDR, under 250 some digits doesn't light, (usually the 0
witch is more
What is your voltage set at? 6.8K would be an appropriate resistance for
these tubes at 180vdc in direct-drive mode, which that clock kit is not;
it's a 1x6 multiplex. Multiplexing usually yields a less-bright display.
There is some debate as to whether or not you should use lower resistance
