Hi there mpukett,
There are several ways to do it.
This is similar to the way Boss pedals do it but you do need the right 6.5 input socket which turns the power on when you insert a jack plug. Just use a stereo TRS socket. (Tip-Ring-Sleve)
When you insert a mono plug the Ring is shorted to ground which turns the unit on.
So TWO Things are happening here,
Input socket turns the unit ON (by connecting the ground to the negitive rail) and inserting the wallwart disconnects the the battery positive passing supply over to the wallwart.
Be aware that the DC socket is a trick to wire up as it has 3 terminals. The centre is usually obvious but if you wire the other two wrong then you can fry your battery.
These Aux power sockets come in many sizes so make sure you use the same dia as the plugPak/Wallwart you use.
Diff dia's, diff lengths, I do wish they would try to stick to one type/size,,
it would make life just that little bit easier.
Use a plugpak that is well regulated and designed for audio use,, some are porely regulated and can add a lot of unwanted noise to your sound.
I've drawn the aux power as "Centre Negative" (Boss) but there are other ways to do it.
Hope it helps a bit. Phil.
