When reading the data sheet, first thing you see is: The defect rate of a lot of -say- tubes should be as low as can be, and not just initially but during The 12AU7 and its variants are a miniature nine-pin B9A base medium-gain dual triode vacuum tube. At a duty factor of 5 percent and at an anode current of 15 mA, the type B tube appears as bright as it would under normal d-c operation.
