Default Mtx terminator tna251 help.

So the blew all the ps fets, and probably the outputs too. Legs 2-3 are shorted on all output transistors. The amp had 75n06 in the power supply which i switched for 3205's and in q1-4 replaced the drivers with mps56-06? The amp powered up however i left it on 9v and it drew over 3amps.

Just to make sure nothing else was wrong Perry, I turned up slowly, but it remained at high current.
