Not too sure what you mean about the PCB being wrong. Correct, you cut off the collector. Just socket Q7 try a bunch of 2n3904's til you find the noisiest or the noise you like and then cut off the collector. That simple.

On the PCB layout, beneath the Q7 outline you can see a track which is making it's way to R49. But it's not a third pad for Q7. The only two pads under the Q7 outline have a little spot which means they need to be drilled and will have Q7's Base and Emitter soldered there. _________________ What makes a space ours, is what we put there, and what we do there. |

Hi The Big Ear (btw, nice nickname ), and to electro-music...
No, the simbol on the PCB for Q7 is definitely right.
If you look at the second page of the spec sheet that you've linked, you will find the pinout of the trasistor.
Remember that usually a transistor pinout refers to the transistor seen from the bottom to the top: you have to look the legs' side...
Do this and you will see that the PCB symbol does make sense.
bye...

Welcome, Big Ear.
I think you have your profile set up not to show BBCODES. That's generally not too useful. That's why your quotes aren't showing up. You can set it using the profile menu at the upper right of any forum page.
