Received my boards as well. Thanks very much. Very flexible board layout and nice to have some zener regulation/decoupling of the opamp.

There are boards left (see my sig) so hurry up to grab the last ones. I may start another group buy next autumn.
Hi Per-Anders!
I just start to ordering the components, but don't find values for P1-P4?
And they are not in any BOM?
(the trim pot.)

These pots are just options if you want a trimming possibility. Normally you won't need it. If you look in the schematics for variants you'll see that they are with red crosses.
Soldering Serpentine is done. I have a 18v transformer. Output of the ssr03 is planned to be 15v.
Now I want to test my work �� what parts do I need to do so?
Are there measuring points on the board availability to measure individual blocks of the board?

If you manage to put everything in the right places then you shall get a stable output voltage and the LED's are lit. Pin 2 and 3 on the opamps shall have the same voltage within a mV or two. The voltage itself shall be 7.5 volts of you want 15 V out and you use a LM431.
Hallo Per Anders
Just a hint regarding your SSR03 BOM.
Here in Germany it was very easy to get these WAGO modular PCB Terminal Block with pushbutton but nearly impossible to the 4 and 12 port versions. Perhaps you change the Block items to the modular ones?

Im using the 24V LM431 bom. Its intended to be on for weeks, but in standby about half of the time ... Also wondering about the trafo,is 2x24V 100VA for maximum load of 1A pr rail OK?
Very nice board, the quality is top notch.

You can built to any pole number. They are like LEGO.

I think it will consume 30 mA but it's possible to tune down the consumption a bit with increasing R17 and R37.
This is true. And they are easy to get.
This is the reason why I mentioned to take these (0256-0401) into your BOM instead of the 0256-0405 and 0256-0405
