Yes, you could wire in a power jack. Take a look here: http://www.smallbearelec.com/Detail.bok?no=93 That explains what hooks up where. And with the pots, they are usually about the same price, and not too hard to find.

5k pots are a little hard to find in the UK i've found. The closest I can get readily is 4.7k. Will this have a major effect on the sound?

No, I believe that should work fine.

I'm a little confused as to how to wire up the dc jack.

'To Board -' is to the ground of the circuit (ground lug of input)?

'To Board +' is the Power V+ of the circuit?

But 'To Battery +' and 'To Battery -'  ?? I thought the jack eliminated the need of a battery?


Help?

Well if you wired it as it says with a battery, it will run off battery when it is not plugged in and will run off wall power when it is plugged in. That is the standard for most pedals.

I see.

I've always taken the battery out when I've bought a pedal with DC jack.

is it necessary to use all the lugs on the jack then?

Also, (assuming i can wire the jack up right) i shouldn't have any problems using 'em to replace jacks for ehx pedals etc that are 9v DC but don't have the regular DC jack?

I believe you would just not wire up the + battery lug and obviously forget about the second wire on the "-" lug. The jack works as a switch, so when nothing is in it, it is connecting those lugs. You can buy a regular jack (usually cheaper) without the third lug if you wish to not use that switching method with a battery.
You should be able to replace given that the jacks are the same size and specifications.

Ah ok. Think i'll connect  a battery snap anyway, in case of emergencies etc.

Thanks, you've been loads of help

Try smallbearelec.com. They should have anything, and Steve (who owns it) is a pedal builder himself who contributes here. Support the pedal building cause!

I'm in Aus down in Melbourne and I've found the best places to get all these parts is Jaycar (www.jaycar.com.au) and Altronics (www.altronics.com.au). They have stores around most places.

Dick Smith also has "some" of the parts but not all, but they are where I get most of my pots and DC jacks. The pots from Jaycar only come in the large 24mm style which isn't what your after. You want 16mm or there abouts.

You could also try Futurlec if you want to shop online (www.futurlec.com.au) but I've had mixed experiences with them. First order arrived within a week. Order I placed last week though seems to have gone missing. Wasn't charged for it though so I guess I'll just order again.

Where do you test the circuit? Do you use a breadboard?

i think Aaron means . instead of wiring the switch in, he wires the circuit directly to the jacks. to make sure that part works  .
and if it works then put the switch in the circuit .
 if it does not work then, then you know the circuit is working, so the problem is with the switch wiring .

then if that is working... put it in an enclosure and if it stops working, then you probably have a short (ground touching something that is not supposed to be touching the ground, the whole enclosure is a ground if it is a metal case once you attach the jacks and pot)
doing it that way just makes trouble shooting easier .
hope that helps.

ummmmmmmmmm i was wondering... how do you tell the difference between an audio taper and linear taper pot on a schematic? i don't see what indicates the difference. all i see is that "(linear)" is on the parts list next to the 5k pot.

P.S. i have built this as my first build and it has got me hooked! sounds AMAZING.

OH one more thing! what is the difference in sound between metal film and carbon film resistors? is there one? thanks!

Less hiss with metal film. For the pots, audio will be indicated or something like 100KA or similar.

thanks! so you would say metal film are better? Also, can an NPN germanium transistor be used for this, and how does, say, an AC127 germanium compare to a 2N2222 silicon? thanks again!

I think you need to use regular Si transistors in this circuit. I use metal film when I can, but it probably won't make much difference.
