Let me share the Proteus circuit ...
BTW, the L7805 missing in that circuit, I think all of you know how to use it.
That is very simple and easy DIY adjustable regulator by using LM388. But it kill me 2 nights to painting the box

I think you talking about the variable resistor is in linear or not?
I also thinking about that before I build it. And there some article in the internet talking about how to make that possible.  But I have no butterfly finger , so I skip that.
