Thought I'd jump in with a question of my own on the same relative subject. I will be replacing a tired copper oxide 1/2 wave rectifier on my Triplett 3413A emissions tester with a 1N4001 diode. Am I correct in assuming that I won't need a voltage dropping resistor as the B+ is fed to the meter and the overall voltage is controlled by the "line adjust" wirewound pot?
