Have you tested the DC servo practically? I have serious doubts that it will work since you have a phase shift far beyond 90 degrees. 180 degrees is oscillation and you have 270 degrees at least. Luckily you can change component values to get it right.

Also, why choosing so odd resistor values?


Yes, the servo is tested, prototypes are shown at DIYhifi.dk - Forside

As mentioned earlier in this thread, the servo is actually quite perfect.. :) And the first servo I have ever seen, without bad influence on sound quality.

Odd resistor values? I do not understand.. All resistor values are E96 standard types... Please explain..
