i replaced a single shorted ps fet. amp turns on and idles at 1.3a however the ouput is only 7vac on the terminals with the gain and lpf cranked. input signal is 1.5ish volts and other amps have no problem getting to clip point off of it. any ideas why? dirty pots?
You'll have to to compare the audio to the triangle waveform. Set the input to whatever you had when you had 7v output.
If you have the tutorial, this is the type 1 class D amp.
