Make sure your wall wart is pumping out a steady voltage close to that required - you would need an oscilloscope. I have heard that this can be a problem for these clocks.
I’m also not a big fan of running tubes near the bottom range of their current specs. It seems to lead to more cathode poisoning. There are various threads where this has been discussed in great detail - with evidence. Apologies if this all sounds like hearsay, but it is based on the conclusions of similar threads. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
