307,
I always thought that transistors were like fuses in that once the transistor blew it was gone.Am I wrong in this assumption?Could the driver's bias circuit be part of the problem?Sorry for so many questions,I love this hobby!!!!!!After all these years I still have soooooooo many questions.

Transistors are not like fuses. Sometimes they have trouble otherways as well as "blowing". You're problem is thermal. As the transistor heats up , it goes into thermal shutdown and as it cools the junction comes back and it works ..:)
