I love it! Great job hwj-d. I have some TEKO cases on their way

But one little caveat are there with my solder posts and TEKO 371. Because they are interference fittings, I can't get out the pcb without destroying two of them (maybe not, i've not tried it yet).
Have you toyed with the temperature compensation resistor yet (400k)? I’m waiting on more thermal epoxy to arrive before I can take another shot at making a heated enclosure.
No, that's one urgent next point to learn for me. Next step is to build this 2*200mA psu as compact as possible. Then bring it together with temp compensation, output other voltages, maybe multiples, and so on.
What's about a kj7e's 10V buffer pcb from osh?

(€: no, first, need to play arround with own measuring values, LTC2057, and so on, with respect to kj7e's suggestions.

I think, TiN and others are right. The measuring possibilities reach their limit with lm399 based instruments. Now I need a K7510...

unattainable ...
You might try measuring two LTZ’s back-to-back, which will give you more resolution. Connect the positive output of two refs to the inputs of your meter, then bridge the two negative outputs together.
Edit: Andreas mentioned using isolated supplies for this measurement.
Yes absolutely. A big playground opens up.
