Vacuum tube (9 pin) prototyping board enclosure

thingiverse

My Custom Br3Dboard for Vacuum Tube Experimentation. I recently discovered these 9-pin vacuum tube prototype boards on eBay: http://ebay.to/2hhFmKj UPDATE: I created a full-scale breadboard (br3dboard) with banana jacks and colors for a common tube pinout (12AU7) to experiment. Red is assigned for anode high voltage. Yellow is designated for cathode. Black represents GND. Blue indicates grid. Green signifies heaters. Your pinout might differ. Check your datasheet. I designed this board specifically for a common dual triode tube but it can be used in various ways you envision. I thought it would be a good idea to enclose my vacuum tube prototyping board just to add an extra layer of safety when working with high voltages (they can be fatal if not handled carefully). You are using high voltage at your own risk. My suggestion if you're new to this hobby is to stick with lower voltage projects (12Volts) like this one: http://diyaudioprojects.com/Solid/12AU7-IRF510-LM317-Headamp
