"I recently acquired a Future Electronics FTC-401 transistor checker. It was made in Japan. \ni cant find a manual for it anywhere. There is a new company listed with the name “future Electronics “ but they know nothing of it.\nI have attached a photo. Anyone know anything about these units or perhaps have a manual?  \nthank you!"
