Here is the schematic (drawn beautifully by my friend Tom Nelson)

And an image of the final Two Comparator Effect circuit.

thankyou so much for sharing these - might get me over my fear of electricity! You have a great teaching style :slight_smile:

Here’s the final, full schematic of my Luminance/Chroma Inverter.

hi @schaferob - just one small question re this schematic - should the Rx/Cx pins on the one-shots also connect to ground ? like in this diagram from the datasheet ? (or is this implicit/internal somehow ? )

I never tie it to ground so it must be connected internally. Any chance that’s the info for the CD4538? (Should be the same but I know the old CMOS version could run at 18 volts!)
