Hi all,
I have problem with this construction:

Buffer working good,but DC stability isn´t very well!When I switch on at out is 240mV and going down to 0V.After two minute stable on 3-25mV.Still going up and down.I did two this buffer ,and doing this both of them.
excuse my english,
regards,

Help is easy : 'cos EB like to listen DC signal , all his connections are DC coupled...If you make feedback loop not as " DC " and connect R 7 through some larger capacitor ( elyt + foil in parallel ), problems will be away....Second solution is to get this buffer into thermoisolated box with regulated constant temperature...
