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.
