Transformerless Feedforward Vari-Mu

D1 = 4007x

+/- 18V will work too and 166 mA should be enough or go with DCWN06A-15.

1/4W should be fine on the sidechain, except use 1/2W on R22.

I didn't have the zener yet when I took the picture and I added it later. It will work without the zener, but it's better if it is there.

R22 1/4 W, got it. Thank you.
