I have a little problem. Not sure if this will help narrow it down.
On Channel 1 the Mute led is shares function with overload detection. If i press the mute button, the led lights brightly. If I remove mute (this just started happening) the led is still lit, just not a bright.
The section of the schemo is
The way I see it the red LED D104 has current flowing even without the mute switch. I'm suspecting the opamp U102A is not functioning properly.
The entire schemo is from gyrafs DIY page at the bottom. This is page 4 of the entire pdf.
Any comments of my sluthing????
