I have finally found the problem with the display on my 312A, on the MHZ range nixie, the 2nd from the first LHS, the neon that drives the photo conductor is flickering. How many hours, or years, of operation does it take before the neon strike voltage point begins to degrade? I may have to start looking at LED substitutes, which I remember being discussed in a previous thread, and clean the range selector switch with de-oxit
