Hi. I came across this thread and it looks like my issue is exactly the same as the one you're describing. I checked the rotary switch and it's working properly. When powered on, all the LEDs light up and then start turning off, but only to the level set by the RELEASE potentiometer (Release at minimum position: all LEDs are on / Release at maximum position: all LEDs are off). The compression seems to be non-functional. Have you made any progress in solving this issue? I haven't found a solution anywhere, and Mjollnir and Toph haven't updated their posts any further. I'm thinking about whether it makes sense to replace U5 (TL064), but as you said, I don't want to swap components without knowing what I'm doing.
