Through the Zero Plane

Some excitement when I got the En129 (ElectroNotes TZVCO) to work. I had a few problems etching the board (see previous posts) and then I had a few problems getting it to work. I then found a few missing resistors from the schematic when I had copied it into the PCB program. Anyway now all is good except for a couple of resistors mounted on the bottom!

Here is the board:
The layout is reasonably tight but there are a few more links that I would have liked. I probably could have juggled around the opamps between the packages to get rid of a few but I was getting a bit fed up with it all by that stage...

This is the result of some very simplistic testing. Looks a bit like some of the photographs that I have seen for the scope outputs from the Teezer and the ZeroOscillator.

Might ask Bernie Hutchins if I can post the layout for press'n'peel to electro-music or somewhere...

It seems you have a a bunch of great layouts.
Any chance for this?

There are links to most of the better PCB's -- Since I don't want to be Green Lanterned a few will stay incognito...
