I recently pulled the output transistors from a Sunn Beta Lead amp that I am servicing. One side had 2N3055 transistors. The gain (hFE) tested 8, 8, and 35. According to the datasheet, those 2N3055 transistors should test 25 to 70.
Do transistors that age or are stressed get lower in gain? Should I consider transistors lower than spec to be bad?
