Rod is helping me. I needed a small board.

My question Stan brought up. Is ground. So dc and AC can use same ground?.

On the half wave. Which I'm using.  Once I get the boards so I can see where things go my plan is to jumper AC in to + of bridge. With a diode.

Then jumper - of bridge to dc neg. A.c. ground will share common ground.

When using fixed resistors. Do you leave one hole open? No jumper...

Riki, yes jumper the diode from ~ to + with the band to the +, and wire jumper the other side from ~ to -.  That makes the ground common. For fixed R2, jumper the pot pad from pin 1 to 2 with the resistor. No connection to pad 3.
