I've certainly had a bad K155ID1 or two...but I've also seen a failed MPSA42 do the same thing in a clock, but only on one tube...any chance you have a transistor failure somewhere?

I don't really know what I could be doing to cause this. I am pretty sure that it is an issue with the chips because I have always had it happen occasionally even when I was just breadboarding and stuff. And the problem would always follow the particular chip, if I moved it the problem would follow. If I replaced it, it would go away for some time. There have been bad batches of those drivers in the past. Jonas from TubeHobby had to replace a large number of them in his NCV2.1 clocks because they had the "0" and "2" digits ghosting. So it may not be your design, it could actually be a problem with the 155's. Are all the ones you tried from similar date codes and in the same packaging type (plastic / ceramic)? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
