The actually question in early days for me was follow:Thanks Tief... this design was AC coupled single rail. I can't recall the exact R/C values used now. It was a long time ago
How I do avoid an electrolytic capacitor in the NFB loop by use of symmetric voltage supply.
The best known solution is a DC offset servo. A better solution for me (especially as modification step) is to find by post 60 about

Only to realize with j-FET LTP or the solution from schematic by post #1 here.
