I've made a LTspice schematic of the board with corresponding reference designators and typical (datasheet and SWAG) parts values. I've attached it, renane to remove the .txt suffix to load into LTspice. You can DL LTspice for free and load it, but I'll post a screen shot image later if someone wants it.

I saw that someone was wondering what the dimensions of one of the chipamp boards was, and while I can't help him with those dimensions, I can put the dimensions of the LM3886 Mono Board up here for people to see. I finally got it populated today and will spend the next few weeks (family, job, house and all) building the enclosure for them. Well, here is the link to the pics:

An externally hosted image should be here but it was not working when we last tested it.

I also ordered and built the LM4780 Parallel board [LM4780 (1)] pics here:

An externally hosted image should be here but it was not working when we last tested it.

And I ordered the LM4780 Bridge/Stereo board [LM4780 (2)] but have not put it together yet. Here are the pics of it as well:

An externally hosted image should be here but it was not working when we last tested it.

Since I was at it, I took pics of the ChipAmp power supply. I am using one per LM4780 parallel amp.

An externally hosted image should be here but it was not working when we last tested it.

I needed something to do this winter I guess.
