Buzzing Atari Punk Console

[Funky_Tomo]

Hey all again.

I just managed to make my Atari Punk Console go, but it has a horrible buzz. What could cause this? Grounding or do i just need shield it? I used a 9.1k for R3 as there were no 10 k.

And is it possible to put a volume pot on this? Could someone draw where and how?



Thanks all in advance!

Anyone?

Use the search button and I think you'll find a recent thread about this, that discussed some possible changes/errors with this layout.  To add a volume pot, just take purple the wire going from the board to the jack and hook that up to lug 3 of a 100K (or so) log pot (try different values), connect lug 2 to the output jack, and connect lug 1 to ground.

Cool thanks. I put a A - 250k pot in and it works great. It isnt as bad when connected with pedals with preamps in it, but alone it is loud and noisy! I had a search but couldnt find anything that could help. Apart from maybe here.. http://www.diystompboxes.com/smfforum/index.php?topic=46468.40
