I just finished my version of the correction amp, is like that of dr. lava but is a bit more sturdy
if someone need it i can send gerber files or copper layer mask
in the list there are 12 50K potentiometers but in the pic there are 6 10K (offset) and 6 50K (gain), what i have to use?
can i use also 81-PV36W503C01B00 from mouser? (cheaper than yours)
