Bruce Heron was looking to simplify the process of testing and prototyping his Tube designs. When testing designs, a solder-less breadboard is a fantastic tool, for the hobbyist. However I have never seen one that was either durable enough or indeed that has the correct connector layout to take a vacuum tube.
What Bruce did then was to layout a wooden board with the required connections for his tubes, a breadboard and other required components. The board has connectors for inputs an a variable resistor. Chock blocks are supplied for routing and components.
Bruce seems pleased with his proto-board and suggests a few more components you may consider adding if you chose to roll your own. More pictures and some further details of the build are available at DIYAudioProjects…
