Whether or not these make a difference (TBD), or were deliberate changes , just a heads up on two differences from the original schematic: The 10k goes to pin 12 instead of 10, and there's also a 2n2 cap between pins 1 and 2.
Schematics are confusing between Fredrik pcb and bom, his own versión for veroboard an Ander's present layout.
1. There's no problem between leg 10 or 12, they 're both outputs.
2.Definetely it lacks a 2,2n cap between pins 1 and 2 of Ic1, you can solder it between A3 and D3. 3. Output cap is 4,7UF on Fedrik' s vero, 4,7uf on pcb bom, but 10uf on schematics. I used 4,7uf, sounds good. With these changes can be verified.
