They had no idea what they even were, Resistor/Capacitor??? I told them they were Rectifiers. Selenium Rectifiers. and they had never heard of them or seen them before. I told them how rotten the smell is when they blow up. Then told them that there were no 1N4007's in existence in those days. We made a lot of stuff before the advancements in semiconductors. When did you first see a LED? Paul w0rw
