Greetings, I have a version 1.0 5 tube nixie clock that I built in August 2014. About a year ago it quit working. While it is plugged in the alarm buzzer makes a plaintive continuous beep. When you remove power three of the nixie digits light briefly and the 5 blue LEDs under the tubes come on and t...

Resistors arrived yesterday. All four circuit boards working again although I note a couple of squares on one board the that don't seem to provide as much power as the others and the pieces only light weakly. What should I check on those squares?

Thanks Tony, I think I finally managed to get some from Allied Electronics after I finally tracked down a good part number. It only took me an hour and a half of searching the internet... I had to buy 10 resistors, pay a $5.00 handling fee and $6.50 for postage for .17 cent resistors but at least I ...

Ok, now I need at least one (or preferably 2 or 3) but here at the end of the food chain they're just not available. Is there an online source where I can buy less than a thousand or can I buy them from you?

unnamed.jpg Is the R1 resistor on the case boards .47 or 47 ohm? I have a board with a dead resistor and am having trouble definitively figuring out what it's value is. The original resistor is reddish orange background with black, yellow, violet, silver and gold stripes. The trouble comes from dec...
