I made a big mistake here:
Mixed up IC sockets and went crazy cause could not find where to put some component.
My apologies go to Dmitry, owner of SSSRLabs, for saying there is a mistake with the kit.
Had to un-solder and replace the IC socket – took quite some time but got it done !
And finally I lost a capacitor …
Many, many thanks for your patience Dmitry!
Current state of work on the SM042 Kotelnikov kit. Another evening and hopefully it is done and WORKS !
