High Performance Regenerative Receiver
A piece of an-inch-thick wood was cut to fit the inside bottom of the box. Wood screws hold the wood to the metal; they also secure the circuit board and other components to the wood. To mount the film-can coil form, I drilled a small hole in its bottom and attached it to the wood using a small brass wood screw. The wood bottom

Components and Methods for Current Measurement
www.vishay.comVishay Thick Film Resistor Products: The RCWE and RCWL are typically 0.0005" to 0.002" thick, which is nearly 100 times that of thin film. The increased thickness equates to a greater mass that is better able to carry the relatively high currents and dissipate the heat across the substrate, as well as better able to manage transients.
