Here's the first sample circuit board. I had 4 of them made just to check the design and correct any mistakes. It doesn't have any of the green solder-mask that production boards get.

Here's the sample board with most of the parts installed.

An extreme close up of the circuit board. Maybe a little too close! Check out the germanium diodes - they're used to get the octave up effect.

There it is... the first OCTRON prototype! I had to join up two boxes for the enclosure because I wanted plenty of space for tweaking. I did this for ZIM, too.

The "underbelly" of my OCTRON prototype.

A closer look at the board. A tad sloppy, but it gets the job done. There's a lot of stuff happening on that small board. I'm cleaning it up more for the next run of sample boards.
