They continuously drop the value of output resistors I don't think there will be any audible change.

Can someone please post a picture of how the potentiometer is soldered on the board? I am mounting these boards on the sides of the case (sides are built-in heatsinks), and it would be nice to be able to access the potentiometer without much of disassembly.

Hanair, I assume you put your boards vertically with power transistors on left and right side. If so please put R19 resistor of 1K5 value normally from components side and add to it 5K potentiometer from the other = soldering side vertically. You will have access to it from the top.
What I also did - I left emiter legs of transistors Q9 and Q5 uncut and straight - it is easy to connect there multimeter probes from the back and measure idle current.
