The original schematics posted by Mr. Pass on the first page ( https://www.diyaudio.com/forums/atta...-ab100-001-gif ) shows 221 for R35.

R35 should be 10e , or just bridge the gap with a jumper . The 10e works well in my experience , lifting signal ground .

Hey @flamethrower1 , here is the last schematic from Prasi , that should be used with his boards . It has the R3 correction of his previous schematic @ the correct 1k , not 100e .

Post 11234 of this thread : AB100 Class AB Power Amplifier

Values are correct for all Prasi boards . The schematic just indicates 2x big caps per rail compared to the 1x cap per rail version

That is the schematic I am using, lessoned learned, trust what it says.
The BOM I downloaded called it out as 220.
I guess if that is the only hiccup, all is good.
