Read Dennis Feucht.
You need to add the source resistor to control/set the Id to BOTH upper and lower devices.
This gets the output offset to close to zero Volts. Trimming one or other source resistor as described by D.F. sets the output offset to zero.
Be careful with maximum dissipation. The B1 has 18V across the two devices. That leads to a high Pmax in the smd sot23 you are planning to use.
The DCB1 is even higher at 20V.

Your attitude on the knowledge required of DIYaudio Beginner Members stinks.
Do your homework !

Andrew , I apologize but giving me something to read is much better. I don't even know what to read about.
I believe everyone start as a beginner. The way some treats beginners is not the nicest, at least for me. You guys have to understand not everyone here is a major in electronics or do electronics for a living. The success of a DIY forum is also based on how tolerant you all are to novices. Else it will end up being an old country club with few old people bragging about their stuff.

Fabrice,I been here at least 2 years before you.I know there is no shortage of knowledge here.But not many are willing to freely share it.Many will show up to help and leave you high and dry.They are doing because of their hightened self esteem and dont want to talk to ignorant guys like me or just because theya re unsure of their self.It is not unusal to find few who approach you seemingly to help with their buisness.

it's not a matter of "free sharing" , those who knows doesn't speak with "anybody" , they do with people they "like" , it all matter of passion and feeling , nothing more , and when they like they give a lot , like me , you and the all world ....

it's the first rule here , you got what you gives .

and I am ok with that
