Here you will find direct access to all the documentation for my various DIY projects. Much of this has been created in response to questions asked buy DIY builders at All the projects and PCBs have been described at groupDIY and that is the place to go to ask questions not answered by the documentation here.. Lots of people have built tube audio devices based on my designs and they have a wealth of experience you can draw upon if you have any questions of problems. They come from all over the world so they are very well placed to answer country specific questions like where to source parts for example.

My friend Pierre maintains a gallery of projects that people have built based on my designs. If you want to see what other folk have built look here:
