Maybe you forgot about me? 😉 I know you are busy, but let me ask you again, and add a question: what is a possible replacement for the 2sk170?

Sorry, I'm not an electronics engineer🙁. I just wanted to get confirmation that I drew the diagram correctly. Now I understand that no answer, was answer "yes" 🙂
Any suggestion for a replacement for this jfet?
Thanks again for your help.

My honest advice is that if you do not understand electronics well, please stay away from these difficult projects.
They look simple, but they are not.
Those people who have been successful building this on their own all understand what they are doing.

Thank you for your attention🙂
I suppose many members of this forum don't understand everything, but still try build their devices.
I take your advice and I'm already avoiding this topic.

It is better to be rude now than to have both of us unhappy later.
Considering starting with something simple that does not need floating supplies :

That is right but in this very specific case you will need to understand what floating power supplies are. Floating power supplies are far from standard to many DIYers (and therefor best avoided).

As I understand it, in my idea the problem is to combine the power supply of the offset circuit with the supply of floating CEN. I did not want to be rude and I always appreciate good advice and do not perceive it as rude.

perhaps not so much when they are floating, it is the moment when they cease to float, that they become problematic 😉
Mr. Rutgers' IV converter is very well documented and does not require more skill than normal opamp circuits.
He also explained in detail why this is his final solution :

The additional current source for the TDA1541 can be a simple LT3092.
Very well explained in the datasheet.
So my advice is to start with those first.

Maybe he should start with a TDA1543 and a resistor. Can't be a simpler demonstration of the principle than that.
A person with decency would not recommend someone who cannot swim to jump the cliff.
Or laughing on the sideline watching him.
