Thanks again, Bob!

I couldn't find a 393 locally, so substituted the lm339 from rat shack. It seemed a reasonable substitution. And yes, the polarity for C1 on the posted schematic is wrong, and it is correct in my circuit. I should have corrected that before re-posting it.

I'll try a smaller cap, thanks for the suggestion. I can see how that might be a factor.
