    Thanks for the feedback Windell. Good news is that the replacement has been constructed and completed without issue, so hooray!

    All the best,
    Nick

    Hi Windell, any further progress on this?

    Cheers,

    Cosmic ray? ;-)

    BTW, I use an Edsyn 951SX solder station (or sometimes an AOYUE 968A with SMD rework).
    No rush on the PCB….I’d be very happy to hear what’s wrong with it (or me!) too.

    Hi Windell, I wish I could give you more info, but as I mentioned I was building this PCB along with two other bulbdial kits and the others went together fine….haven’t changed my rig or solder in anyway for many years…Just finished building some more nixie tube clocks with the same equipment too, no issues there either…not sure what to say! My bulbdial is still working after many years too! ;-) Perhaps a PCB solder track short to ground somewhere that’s very very tiny?

    Hi Windell….did you receive the board OK? Any idea what was wrong?

    Cheers,

    Thanks Windell, I’ve sent an email…just hope it’s not an embarrassingly easy fix that I should have spotted!

    Cheers,

    Hi Windell, I’ve replaced C3 and C6, played with the mechanical side of things (tapping, bending LED’s etc) and it still does it..I’ve checked and double checked the layout, the other capacitors, swapped IC’s (as I’d mentioned before) and I can’t see anything untoward. I’m stumped. It’s probably something obvious, but in my defense ;-) I just finished the other bulbdial and it’s working fine…any chance I could send the board your way for a look?

    Thanks,
    Nick

    Hi Windell. I’ve been trying to figure this out and I’ve come up short. I’ve replaced a couple of suspect LED’s, still the same issue…in fact I’ve now seen completely unrelated LED’s illuminate unexpectedly…it’s like there’s a ghost in the system! Just to make sure I’m not completely crazy, I just finished the Blue ring on another kit and its working flawlessly (a few of these boards were in a backlog of kits I had…and Xmas is coming up…these things make pretty nice Xmas gifts!). This board appears to be particularly sensitive to touch capacitance from my fingers and will occasionally shut the LED’s off or even advance an LED or two at a go….not sure what to do next…any ideas?

    Thanks,
    Nick

    Thanks for the quick reply Windell! What I mean by flickering is that when the unexpected LED lights up it flickers on and off randomly (like you have a poor connection on something), then the next time around the ring it wont light and then it may again the next time, it’s kind of random….odd. I will check the areas you mention and check for stray debris with the magnifier…I’ll also give the LED’s a gentle ‘tweak’.

    Cheers,
    Nick
