Default XGC Board Try

Hello,

After building a LM3875 VBNIGC, i planned to build a PA100 to driver speaker based on scanspeak 15w4531g00/vifa xt25. These two in 9L box have 5ohm impedance and 87db sensitivity.
After reading GCsupersymety this option seduce me more than the PA100 since i have a built bosoz in stock. So here my latest XGC Board try. It's done under Proteus. I have too much problems with eagle.... so i follow under proteus.

The Metalman modify schématics. I intergrated the end part of the 338 regulated subbered PSU. 330nf from these will be direct soldered between lm3886 +/- pins. Electrolytics/small MKP near Lm3886 are 2200µf/50V // 100nf.

I have been really wanting to build a SUSYGC I will be intently watching this thread. A PCB group buy would fully rock.

I've no possibility to produce board for group by but i can give proteus files if some want. What would be nice is that some one can validate this board.

The PCB looks really great!
I' ve been checking the layout and didn' t see anything wrong, but I' d be nice to hear some PCB guru' s opinion...

BTW, I' d be interested in having a couple of PCBs, if there will be a GB...

I'm always down for trying a new GC variant Someone should get a GB going if the layout is good (with full credit going to Idefixes, of course).

I'd check the board, but I have the PCB analysis abilities of a mildly retarded squirrel.

Yes that's what i read in the dedicated topic, but since no news. My way is a little different : the final cut is not a GB, but my own use since ŕ be abble to realise board at home. Of course every DIYer can have acces for his own use the board file under proteus. But for this time i need some help to check the current version and to optimize it. I have all necessary parts to built two mono blocs. Psu based on latest carlos version with 300Va/2x25v, mur1560 rectifier bridge,mallory 22.000µf/40V Cap, Lm338T regulator per bloc. I have two rubbish heatsink (200x200x40mm)

So the board and her optimisation are the last point to progress.

Well, if somebody is going to organise a GB, it should be done in a way so that Idefixes gets his boards for free...
Just my 0.02...

Cheers,

Bruno
