Setback no tails question

[Robusto]

If I want to build the Setback Delay and omit the tails footswitch, are both C9 & C10 (two 1u back-to-back in opposing directions) still necessary?

Thanks!

From the Setback build doc:

If you don't want the Tails switch it's easy to defeat. Simply solder a jumper between the TLS1 pads on the PCB. Leave the TLS2 and LED2 pads empty. You can also omit R16 and R17 in this case.

You'll still want to block DC from the NE570 pin 11, but instead of equipping both C9 and C10, you can strap one of them, and replace the other with a 470nF non-polarized cap. That's assuming you omit both R16 and R17.

Cool, so the electrolytics  are pointed in different directions. Should I keep the + forward or - forward cap?

Doesn't matter, since you'll be installing a non-polarized cap.  Strap one out, and replace the other one with your 470nF.
