Thanks for the reply. I don't have an Oscilloscope. The night light=20
circuit is interesting, but as I said the boards are made. I had asked=20
on this list several weeks ago how to handle 24 VAC LED's and that's=20
where my circuit came from. I did test circuits, but when I ordered LED,=20
I must have missed something. I have some bright white LED's that I=20
changed the resistor to  5.1k to dim them a bit. These are indicators=20
for a residential HVAC system. There are 3 hear sources, heat pump,=20
electric resistance, and natural gas fed by our well that can get low=20
pressure in extreme cold weather. The unit is quiet, and hard telling=20
what is actually in use, giving use to the LED's. On the added cap, you=20
are saying put it parallel to the LED and diode?
