Hi all

Power supply mosfets blew in the amp. It has two transformers. Each transformer has 8 mosfets in all i.e. 4x4. So total of 16 mosfets. It has pnp transistor that drives them blow also. And I cant see the value of it. Can anybody suggest good driver pnp transistor?

What PNP transistors in that package do you have on hand?

I am thinking MMBTA56. I have these.

Those are OK.
