I got the parts for my second WHAMMY from various stores. The pricing from diyAudioStore is pretty good, but I decided to part this one myself. Pricing to get everything directly was a little less, and I was able to get a few extra op amps and other stuff to test as a result.

I got this illuminated power switch. AudioSan on DIYAudio suggested wiring this way to have the light on when powered off, and off when powered on. I didn't like that approach, but I'm documenting it here:
I liked that switch. But i would use wiring diagram 5 that is not shown. Switch open, ligth on. Switch closed, light off. That could be done by linking NC to LED positive, and NO to the device. That way you could have a red backlight on the powerswitch when the amp is off.
One thing to note. I don't think the wiring diagrams and the explanations are correct. Double check everything.
The "+" pole is for the light.
"NO" is connected to "C" when the switch is depressed (on)
"NC" is connected to "C" when the switch in out (off)
I want the light off when the switch is off, and the light on when the switch is on. This is diagram 1.
Well, as of 2019-03-27, here it is. I first used solid core silver wire sleeved with cotton, then heat shrink on both the input and the output, but there was a nasty hum. I changed the input wire to shield mic cable, and most, if not all the hum went away. I also grounded the pot, and that helped too. Next is to get the front plat milled, then drilled, and finish this puppy!
