Default bpa 200 or a good gainclone...

I use to be in the electronics industry hand and foot. I always wanted to make powerful amp that SoUnds good. I know how to make pcb's. I know how to trouble shoot. I want a good PCB layout for a BPA 200. I have most of the parts for it. Help this newbie out. Please. Oh, schematic would help. I have the one for the PCB AN-1192. I have decent power supply skills. I just want to get my feet wet again.

Thanks.

Here's something similar. Keep in mind those power ratings are load related. In a recent LM3886 x 3 project I learned the sheer output volume with an 8 ohm speaker was about the same as a single chip. I'm not sure if that applies to all the multiple LM3886 designs, but it certainly was true in my builds.

It is true for parallel amps. Bridged amps will give you higher output power.

pacificblue,

Are you aware of any proven bridged LM3886 designs other than the Shine 7 BPA-300 type? Something that bridges the chips on one board.
