Have you found the reason for the failure of the 2N176?

You could use the NTE equivalents NTE104 or NTE121. These may be expensive but they are the substitutes. But you have to make sure that the new one doesn’t burn out.

You should be able to use a PNP silicon power like the 2N3792, but the bias has to be changed. Another issue that might occur is silicon power transistors have much wider bandwidth and might oscillate if the circuit doesn’t prevent it.
