In this video:
We are setting ourselves up for safety by building a testbench setup for old tube radio receivers. This will come in hand for future restoration videos. I will walk you through a brief introduction to an isolation transformer, variac, and current limiting device (dim bulb tester). The latter of which we will need to build from part available at my local hardware store.
