I have tried these parts doesn't work for me:
D1 1N4007
D2 ZFC15v
for caps 220nf I have 270nf/100v
for caps 1uf I have WMA/100v
and consider LM chip in your picture also I have one without metal back just IC in black
anyway at your diagram in post 1 you put D1 to the right at your picture you put it to the left opposite side, and the resistor are different.
my question is what I could replace for parts cause not all available here, and does diode here effect the general diagram or just for protection as you post?
as I can notice the data sheet for LM have also different parts,and I'm really confused.

This is correct schematic and layout,

Did you click on it to make it larger?

The expand point may not be so obvious on this image.

In the bottom left corner after clicking on the image there is a square made up of arrows if you click here Uriah then it will expand to full size

edit: note you need to move the mouse over the image for the expand arrows to appear too! (at least in firefox and IE).

Tony.

Wow, that does get a lot larger once you showed me the expand point. Thanks for that.

Any chance there is a DWG file available for the PCB and PSU (comp and solder sides)? I have access to a benchtop CNC and would like to try to mill a PCB.

Anyone have experience with that? Words of warning?

Peace.

I dont have one but I have a suggestion.
I use this software and it is extremely easy to learn to use. Literally minutes and you will draw your first line. Everything is self explanatory. Obviously I am very pleased with it. It does output HPGL which is what you need I think.
Sprint-Layout
Its called Layout50 and its 40Euro. Its costing a little more every year or so. I think I paid about 50USD for it several years ago. Anyway, its worth it to me and you could whip up a board for this in an hour or so as long as you had all the component footprints already. You would have to build a footprint for LM3886 but thats real easy when you have the datasheet to help you.
Hope its not to off topic. Just a great program for guys like us.
Uriah

Uriah, thanks for the idea. Software is not my issue. I have AutoCAD Inventor and software to program a CNC available through work. The CNC software will open DXF files which I can generate from DWG.

Now, as I am a relative newbie to all that software: can someone advise how to turn a PDF/JPEG into a DWG through an import? Sorry for slightly OT.
