Need help figuring out PWM output through a Mosfet

[dangerbird]

Hi,

I'm working on this car amplifier. The 3524 PWM chip out puts a square wave that goes to the gate of the P25N06 Mosfet. My square wave looks okay out of the PWM (although the Duty cycle is not what I expected) but the output from the Fet looks awful. I have the Fets disconnected from the transformer and each other when I test. When I breadboard the circuit the PWM output looks better, but I still get crappy output from the Fet. I've tried several different Fets and 3524 chips. What am I doing wrong?

Best post your photos here.

Sorry, wasn't thinking.

Not into power system inverters but i'd say the transformer would have an effect on the output as would the frequency level.

You are probably correct. However, I have a shorted transformer, so I'll have to fix that first. Thank you for your help.
