CAT# AMP-8610
$7.95 each
Based on the PAM8610 chip, this little board just needs speakers, power and a signal source to provide lots of crisp, clear stereo sound. Operates on 7-15Vdc. The audio source (ie. Cellphone, MP3 player) provides the volume control. Clearly marked solder spots for easy assembly. 25 x 30mm pc board.

Good luck testing these!
These little boards are definitely not breadboard-friendly. You have to use a speaker for the load, because a 10-Ohm resistor 1/4W WILL burn up when hooked up to the differential outputs. I increased the resistance to 470 and was able to get the output to show up. The SW inputs WILL stop the board from generating outputs if shorted together. Gonna have to search the parts bins in order to find a small speaker for further testing.

Great little amplifier
I used this module to create a low-power acoustic guitar amplifier. I connected a woofer to the output of one channel and a tweeter to the other channel. By including a potentiometer on one of the inputs, I am able to achieve very nice fidelity in my acoustic "blend". I built the amplifier in a little plastic box and had no trouble getting it to work. I glued a little piece of metal onto the chip to act as a heat sink, but in retrospect that was unnecessary, because the chip gets warm, but not hot, in this very efficient amplifier. This module is a great utilitarian amplifier, and I highly recommend it.

Q: Seems like a vol control is possible on IC
The IC spec sheet says gain is controlled via a analog DC level in respect to a reference voltage. Essentially a pot could provide this... if i could remove a SMT resistor.

Amazing Stereo Amplifier
The module was simple to hookup and performed very well immediately thereafter without the addition of any other components. My only question is about the two "SW" connections to the PWB - which I left unconnected. Connecting them through a switch should either "MUTE" or "Shutdown" the amplifier, but I'm not sure about that. If anyone knows what the "SW" function is I would appreciate finding out about it.
