Fetrons actually came...It's "FETRON." Fetrons actually came from the telecommunications industry back in the day when they were switching their equipment from tube to solid-state; the Fetron allowed them to retain equipment that would otherwise have been scrapped by eliminating vacuum tubes from it. However, they soon found out that high-voltage spikes from lightning and other sources were all over telephone lines; vacuum tubes are for the most part indifferent to HV spikes, while FETS aren't. Bye-bye Fetrons...if you like tubes, bully for you. *I* certainly do; I don't see buying a top-end tube amp and then stuffing it with fake "tubes" full of transistors. Why bother?
