Is there a way to wire up a headphone jack in a ruby amp so that when headphones are plugged in, it automatically bypasses the speaker. And to get sound out of the speaker you just remove the headphones?

Theoretically wiring the speaker and headphone out in series wouldn't allow sound to get to the speaker regardless of headphones being plugged in or not. And parallel wiring would still let sound get to the speaker even while headphones are plugged in.

I'm trying to work this out for a Noisy Cricket which will be housed in a stompbox-sized enclosure.  The Kalamazoo Amp Field Guide has a diagram from a line-out jack which would be a good starting point for study:

.

"internal speaker" would become your output jack if you're doing a stompbox enclosure. "Output Xfmr" is your board.  Hook up the ground from board to the 1m resistor and to the ring.

A beginner asked me which jack to buy for this mod. Looking at the schem and what's available, I found the 1/4" Switchcraft #13B (godawfully expensive) and the Mouser/Kobiconn 161-0035. I don't presently stock either one and would like to for the convenience of the many builders of the Ruby, Noisy Cricket, etc.

Can anyone confirm that they have used one or the other of these satisfactorily?

As far as a smaller version, the only possible thing I saw at Mouser was the 3.5mm Kobiconn 161-4034-E. I think the circuit is right, but it is surface mounted. Anyone try this one?
