Hi! I have a circuit board which has a small transformer mounted on it which I believe is bad. It has a sticker on it with '4080' on it. The Board runs on 24v DC and outputs 50v - 100v DC @100ma. This is a power source for an old gamewell fire alarm system. The gamewell circuit which hooked to the board shorted and got really hot, now I get 0v from the board.
