Hey Ya'll,... I am building the 36 watt layout by Ritchie,.. but I want to keep both sides of the amp separate like the original 18 watt circuit,... Looks like this layout combines the signal to one side of the PI and the other side of the PI is strictly for the Negative feedback loop??

I want to convert it back to one channel for each side of the PI. With NO negative feedback switch. How do I do that...?? What changes do I need to make to the layout to accomplish this? Are there any component value changes?

Thanks a bunch....

Please post a link to the diagram you're using. I haven't paid any attention to circuits with NFB but if you post it I can probably help.

Take a wire from the junction of the 56K resistor and the 100N capacitor straight to ground. Delete the NFB switch, 1K5 resistor, 27K resistor, and the 100n capacitor.
