Well, I have never used a series resistor yet but once I DID crack a quartz.
I was experimenting with a 32k one with different cmos gates (1-2-3-4 of them)
and different capacitors. I even tried extremeli big values such as 1nF
and the quartz was blown in a few seconds!

Could you show me any link about this?

Best regards
Les
