Maybe someone can lend a hand here,
This baby came in with blown irfz44's in the power supply. Replaced them, got the power supply working.
I power up the amp and discovered that the irf9640 begin to over heat within a few mins of turning on. Mind you I have oscillation.
You'll notice this has 2 amplifiers, both are doing the same thing.[image][/image]
