Front panel design and module placement.
|Two panel configurations that can accomodate DIY kits|
Tone's top tip: When mounting DIY2 closely on the left of DIY1 (i.e. 20mm hole centres) crop the centre (wiper) pins of the pots close to the PCB - there is a very small clearance but this will ensure they don't touch or short out on the jack sockets; If you fit DPDT switches in place of any jacks then you must crop the the pots as described as the switches are taller than the jacks.
DIY Prototype Board Layouts.
The following diagrams show the connectivity of standard components such as pots and jacks, the tracking to show which pads are connected and some ideas for mounting LEDS and switches. The fainter images are useful for planning your component layout. If you want higher res images please request them on this e-mail link.

Wiring Hints and Tips
Kynar wire is my recommendation for wiring the DIY boards. It's a very thin single strand wire made of a 0·25 mm diameter (30 a.w.g.) silver-plated copper solid conductor with Kynar™ insulation. The overall diameter is 0·5 mm; it's easy to strip, even with low-cost strippers, and it resists run-back when soldering.
I've tried 1/0.6 equipment wire (e.g. Rapid 01-0315) but it is a bit too thick and the insulation runs back when soldered which could lead to inadvertant shorts. It is usable with care but it is not recommended.
