Ahhhh, Richard, your armour and weapons rattle as you come down the hall...

Well, it doesn't flash, and it does seem to work... albeit in a bit of a
"sloppy" fashion (tuning is sloppy as to light changes in the REF led)...
and you are correct, the 100k (and the 1k is there in series too) is barely
enough to keep from burning out the leds and a kludge...

If you HAD to make this circuit work, I am interested, and certainly I think
you of an intellect capable--what changes would you make--keeping as much of
the original circuit as possible?

Warmest regards,
John
