Most of the projects described in Nuts & Volts can be built with readily-available, relatively inexpensive components from the likes of Digi-Key (www.digikey.com), Jameco Electronics (www.jameco.com), and All Electronics (www.allelectronics.com). Furthermore, in the rare cases in which the project author doesn’t supply the printed circuit board (PCB) layout, it’s typically a simple matter to use one of the free or inexpensive PCB CAD applications. Thanks to extensive libraries of the latest chip and surface-mount components, a layout is seldom more than a few dozen mouse clicks away. However, when it comes to tube-based projects, it’s a different matter.
