Do you have a tin drop in J1-J4 on the solder side?

Finished soldering the boards with parts from 24V BOM, LM431. Now im waiting for the transformer for testing. Very nice boards and easy build so far.

I used terminal blocks 651-1864451 and 651-1864477 from mouser(along with all the other parts). My heatsinks are smaller than in BOM, i might end up attaching them to the chassis(when i order and get it).

Negative side
Positive side
Both sides

Do I have to?

Yes, they must always be connected, either on the pcb or in a remote sense application.

just for understanding was is the functional different between R25,26 = Wire jumper and J1,2,3,4 = tin Jumper?

Pin 7 is interesting (not pin 5). What is the voltage on this pin?

What is the voltage across the LM329?

Are both halves behaving the same?
Is it possible?
+Vout against gnd = +15,85V
-Vout against gnd = -15,85V
first hope germinates...

Are there any measure point I could check?

I think I need a lot of praxis to get better...

If the voltage on pin 2 and 3 on the opamp is the same with a few millivolts, then the regulator works properly. A small remarks about your soldering joins, warm more and let the tin float through the hole. Right now it's too much tin and not heated up enough. Otherwise, good work. Don't forget to solder the heatsinks.

Pin 2+3 are the same
but they are different on the "+" and "-" side of the pcb
is this OK?

at the soldering joins I will work again.
at the end of the day it seams so that I managed to finish my first real DIY soldering ;-)
Thank your for your support and patient with me.

Please notice the pin 1 marks on the opamp. That is the important thing. Anyway, if you have a very stable output voltage when you load the outputs, then it works.
