Thanks for replying. Always good when simulations match measurements! I have since tested the same circuit with BFU590QX, and they perform about the same. So we have three transistors that perform about the same and the 2N2222 that is not as good. My only test with 2N2222 was at 10V. I'll test at 12V soon, but I expect the results will not be as good as the other three.
