Super Gain Clone and Compact3886 are chip amps, discussed here:

Bob Cordell's Super Gain Clone PCB (LM3886) and a stripped-down version: Compact3886

The companion power supply board is small and purpose-designed to work with them:

PCB available: PSU for Chipamps , such as Super Gain Clone and Compact3886

If people sign up to buy a total (across all three board types) of 100 boards or more, I'll collect the money and send the CAD files off to fab. Then when boards are delivered to me, I'll ship them out to members who ordered.

Price will be $2 per board if total volume is less than 200 boards; dropping to $1.50 per board if total volume exceeds 200 boards. Plus a fixed $6 per shipment inside the USA, $16 per shipment to rest of world. No more than 10 boards per order, please.

No payment is needed today, just copy the list below and add your diyAudio username at the bottom. Please indicate how many of each board type you pledge to buy, using the same format that I used. Thanks!

When new pledges have stopped appearing, if we've hit 100 total boards, I'll halt the GB and start collecting the money (by sending you a PM).

For example, I pledge to buy 2 Super Gain Clone boards, 4 Compact3886 boards, and 3 PSU for Chipamps board.
