If you are still slow with the 10pF, a 12pF is not going to do it. The relationship between the crystal and load capacitor is critical, and it is therefore a mystery to me that so many (of the cheaper) are sold without the specifications. Anyway, if yours is a cheap Chinese crystal, try some other ones, perhaps you just got a bad one. Generally I always like to get a good brand name crystal. If you want to play with the one you have, try something lower yet, 8 or 7pF.
In general terms, and within limits, larger cap slows it down, smaller cap speeds it up. Sometimes (if you use 2 caps) using a slightly different cap on one leg of the crystal can make a difference in the final frequency.

I have a nice question to ask you guys if you can give me some help. I builded a Nixie watch, It works good, but I'm having a little bit of time delay, 1 min within 6 hours. At the first time, I had 6 min delay for 6 hours aproximately. I investigated the relation of the cristal and the capacitors you need to install with it. First, I had 22pF for a cristal that requires 12.5pF, giving me that 6 min delay for 6 hours, then, I realised these and installed 10Pf capacitor and the delay decreased to 1 minute for 6 hours, and I just ordered new capacitors of 12pF to get more closer to the manufacture requires, So I imagine that the delay is gonna get less. ·Is there any way to make this time delay shorter? ·Do you recommend me a tipe of cristal that is really acurate to install on my watch? Thanks a lot nixie lover's -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
