Reuploaded as the forum software has corrupted the original ZIP at some point.

For some reason forum software updates keep breaking zip files so I'm uploading it again, please ignore the previous link.

Apologies for the late reply, a direct email would be faster as I don't always check here. Have you tried another 5V supply?. After that it would be check the current being drawn and that 5V is reaching the PIC, also if anything is getting hot. If the nixies flash on then T12 and the PIC are probabl...

Try a google for 1.048596

If you had 2 clocks running in series they would display '1.048596'. Probably.

It made more sense as a reference back when I designed it.

The replacement sensors we have found for IC4 (as Sharp have discontinued production of the original and there are very few alternatives with no internal AGC) is a bit more senstitve than the original. Try covering about 3/4 of the window with heatshrink for now. A software mod will probably be need...

Reuploaded as the original was corrupted in the forum crash.

The first thing to eleininate is the LED - the blue LED is in series with the MPSA42 base and can sometimes cause problems. Just bridge it for now to see if there's any change. The high voltages and resistances can make taking readings a bit confusing so replacing suspect transistors is the easiest ...

Check the anode voltage is reaching the nixie itself, try removing a working tube and comparing the waveform.
