IIRC, the RK05 has an external circuit breaker, but no exernally mounted individual fuses like the power supplies from the late 1960s. I'd suppose your problem is some kind of loose component or connection, but I couldn't suggest where to look. -ethan ===== Infinet has been sold. The domain is going away in February.
