I adjusted the voltage to 200V and used 22K as anode resistor. Adding the biasing network (47K for each cathode and then 150K to B+) did the trick. Now i see 52-57V on the different extinguished cathodes :D
I tried using the “No connect"-pins as anodes with varying success. The best readout is obtained by using the pin4 (at least on my tubes) // Per. > On 08 Jun 2015, at 00:19, Dekatron42 <[email protected]> wrote: > > Also do some tests where you raise the voltage to 200V with a correct anode > resistor as some of the Russian datasheets mentions a minimum anode voltage > via an anode resistor of 200V to get proper function, 180V is a bit low. > > You can also try to connect all three of the anodes together, pins 4, 10 & 13 > to see if it alters the behaviour, or use any of the pins 10 or 13 instead of > the pin 4, just use the correct anode resistor and all will be fine. > > /Martin > > -- > You received this message because you are subscribed to the Google Groups > "neonixie-l" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected] > <mailto:[email protected]>. > To post to this group, send email to [email protected] > <mailto:[email protected]>. > To view this discussion on the web, visit > https://groups.google.com/d/msgid/neonixie-l/68ead973-8d87-4602-98a1-92fe5d68f9f5%40googlegroups.com > > <https://groups.google.com/d/msgid/neonixie-l/68ead973-8d87-4602-98a1-92fe5d68f9f5%40googlegroups.com?utm_medium=email&utm_source=footer>. > For more options, visit https://groups.google.com/d/optout > <https://groups.google.com/d/optout>. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
