LM3886 PCB request

[ingrast]

Some notes:

You will need a +/- 28 VDC supply in the 500W class to get the full rated 270W (8 ohm load for both channels).

You may either select lower voltage supplies down to +/- 15 with reduced power output.

You can also choose to not install U2 and U4 for example, and connect the loads from X2-1 and X2-3 to ground instead of X2-2 and X2-4 respectively. In this case you will have half the output capability for each channel.

Of course other arrangements are possible also.

Good luck and enjoy!

yep. I did.

Worked excellent.

Here it is on my website, scaled for printing:
