Blown up, split in 2 finals?

You may have to test all your caps they should had blowen first or a protection diode before the finals.

Just popped both finals again. I knew it couldn't be that easy.

Sounds like it might be time for a new radio unfortunately... If you cannot diagnose the problem yourself, then you would have to pay a tech to take a peak at it.. Not sure what that radio costs, but by the time you pay a tech and or whatever the cost is to fix it , you might be better off spending the money on a new radio.. Good luck.. Let us know how you make out..

Check the voltage on the gates of the fets. There should be a specified voltage in the tune up section. Should be no more than 5 volts maximum. If the voltage is too high that's what is blowing your fets. Many things can cause the voltage to be too high, open resistor or a shorted diode. If you give up my offer still stands!

I will probably save it for a winter project. Don't want to waste much time at the bench if it isn't frozen outside.
