I have just finished building #149 for someone else (after doing my own) and it worked first time round (http://www.dompselaar.org/x0xb0x/149/x0x149_02.mp3) but on closer inspection there is a constant background noise in there. It also amplifies VR8 slider movement. I tried a replacement for VR8 (different type and brand) but that sounds exactly the same. The noise seems to be present on VCA output anyway. I can see it on the scope. Power lines are clean. I would've just put this down to it being old circuitry, but since my own b0x doesn't have this, it must be something else.
Any ideas?
Here's the background noise (much amplified) with me moving VR8:

There's a suggestion from someone on the SDIY list that it doesn't actually sound much worse than a real 303. Maybe I was just lucky with my dead silent #082?
