Nyquist Aliaser PCB design, unverified...

[AdamB]

Hey guys,

I've been meaning to attempt to build one of these crazy sounding nyquist aliaser boxes for a while, but haven't found a pcb for it yet. Here's my first attempt at a layout based on the info over in this topic:
http://www.diystompboxes.com/smfforum/index.php?topic=40860.0

Heres my layout. It's very messy, but it *should* work? The only things I was really unsure of where the power/ground connections to seperate the clock and +9V rails, but I think the way I've done it is ok? But if someone with more experience with this sort of circut could take a look and check it out for me that would be great.

If anything is wrong I'll correct it and upload it, hopefully the end result being an easy to understand nyquist aliaser project for simpletons like myself to enjoy.



Both black 'JACK' pads go to ground on the jacks, the green 'gain' pads go to the gain pot, the other 2 green pads at the top left of the board are for sampling frequency. 'In' and 'Out' pads are for signal in and out, and are blue. +9V is the red pad on the right side of the board, it then goes through the resistor to give 8V for the clock (and also the same resistance to ground gives the +1V, right?). I think I might add another space for a resistor where those 121R resistors go, so that you can easily put in exactly 120R + 1R on both sides.

Has anyone verified this? I'd love a crack at making one of these, they sound awsome!
