On the Tonepad PCB Layout it shows a Transistor which covers 4 holes on the PCB, I thought that transistors only have three legs therefore only needing 3 holes on the PCB.

Also, there is a black line which near the 3rd lug of the 10K pot, what is that line. Is it a wire?

Sorry, It is hard to explain.

But thanks in advanced.

Only three of the leads are going into the holes. You might be mistaking the symbol for the transistor as a hole.

^But on the PCB "ready to transfer" layout it has 4 holes

its just got the 4 holes so you can mount it with 3 legs in a row, or with the middle offset.

if you're soldering directly to the board, the offset middle leg can be easier and more stable.
if you're using a socket, they're usually all in a row, so you'd use the ones in a row..


and that black wire's just a jumper wire, yeah.

So, I'm just soldering the transistor legs in the row leaving one of the holes

Also, am I just soldering a seperate wire (Not the wire from the pot)?

in this case, it looks like you could just solder the wire from lug 3 of the pot directly to the bottom of that black line.
the reason it's laid out like it is on the pcb, is to be neat, with all 3 pot connections together at the edge of the board.

so again, either way will work. it's just a layout thing

Cheers, EDIT: Also there is only one hole for a 9V Battery, shouldn't there be 2, one for positive and one for negative, also there is a symbol next to the 2k2, which has a G in the middle of it? What's that?


Cheers, (as you could tell i'm a noob at this stuff, I just want to get started with a project)
