Your last post might contain the solution. But I prefer to ask again. Are you sure the C11 and C15 must have 22Pico? According to the BOM list (Github), C15 is specified as 100 pico....

edit:

I think I found the mistake. The reference to C11 was entirely correct. I love our Chinese, who seem to be up for a joke from time to time. Instead of 22pico, they labeled a capacitor strip with 220pico capacitors as 22pico. Someone probably thought binary 0 or 1 (220 or 221 ...). Oh, that's right ^^.....
Now that I've replaced C11, it also works with fixed resistors. R3 with 4.7K -> J2 2.6V- Almost perfect....
