GC PSU PCB comments wanted :)

Ok, so here it is. Scematic closely (if not identically) corresponds to carlosfm's unregulated psu with snubbers.
Any comments?

btw, the image is 300dpi

And here's the amp itself.
LM3886, modified RoadKill's pcb.
And yes, I know, I shoud've used polypropilene caps wherever possible but they are very hard to get here and are a bit too pricey. I just hope my amp won't oscillate

the layout looks good for me,what is the footprint size of C3 and C4?

It would be better if the corner is a little softer.

Diameter 35mm.
Which corner did you mean?

digi01 · 14th December 2004, 06:56 AM

i have do some modify use paint

I mean, that PCB of PA is uncorrect - pin 1 on output must be grouded.

wxn · 14th December 2004, 08:23 AM

Upupa: no. That's a feature of RoadKill's design, it has been debated and seems to be good thing. After all, I can always connect these tracks or even ommit zobel...

digi01: thank you, the corrections make sense.

wxn · 15th December 2004, 05:55 AM

No more faults spotted?
Good, I'm off to make some PCBs then
