I’ve been going through these videos as a refresher course. Prompting me to actually think again. This one where you dropped 120V down to 85V with a silicon diode shook me out of my stupor. I thought, hey, no, silicon diode ... only 0.7V forward voltage drop. Oh wait. Half wave rectifier. Vrms = V peak/2. Duh. Kinda rusty here but it’s starting to come back. Good job on these videos!
Hi! I assume by this that your radio was designed to operate on either AC or DC, since the rectifier in the power line means the tube filaments are all getting just DC now?
