It's going to take many more hours, most likely. I probably have more than 100 hours in the last board I laid out if you include all of the revisions to get to the final board. Yours won't take that much time but you can't expect to have it done in a day or even a week. It takes time. Everyone who has built boards has been through the same thing.

Why not simply copy the layout of the other board?

Hello Perry


Yes i would like to copy the layout of the other board....but it's difficult to place components at good place with routing etc....

I spent yesterday and today to try and build this pcb "because i'm sure it will work" and i get discouraged.....

i don't know what to do....

All of the layout work is done. Place the components in precisely the same location on your board.

Someone will have to produce the layout, it's not going to be readily available.

Some people are driven to do this sort of thing and will take whatever time it takes to learn to do it. Others see it as a chore and therefore don't enjoy doing it. If you're the latter, you'll have to wait until someone produces a board. I intended to produce boards for sale but there wasn't enough interest due to the cost of the boards ($25 each, my cost). I never even bothered to have the latest version printed.

Hello Perry

Yes ! i finish the schematics with no problem or errors

In fact i found a schematics based on IC SG3525, the schematics is more easy to read than the blaupunkt smps....

I have bought the scope 2x20mhz i wait for it now

I will build the pcb soon

A scope is really nothing more than a voltmeter with a graphic display.

The first thing you should do is to get it to lock on a the calibration waveform. If you need help with it, post a high resolution photo (good enough to read the text) of the front of the scope.
