I should also mention that one suggested replacement for the 151-0367-00, the KSP10BU, has something like twice the C-B capacitance, so any circuits that are sensitive to that parameter will suffer degraded bandwidth.? It could be that trigger stability might be impaired at high frequencies, for example, if the transistor is used in a critical part of a sweep circuit. You want a sub that has not only a similar ft and voltage rating, but also a similar max Ic (since that is a strong correlate to Ccb).

So, the tester is the problem, and not the transistor. Based on this set of results, an automatic "replace on sight" policy for these transistors based solely on a component tester's say-so seems unjustified, especially since the tester is most likely to make an error when evaluating possibly expensive high-ft devices.
