They have been out for about a year now, haven't heard one.

The 15W is at 4R.

Don't forget to buy a supply, 40VA at 12V is needed to hit 15W/4R X2 at 81% efficency.

A 40VA wallplug will cost more than the amp does (as low as $21).

Hmm, does Target sell them at the store? I might have to head down and take a look. To bad we can't see the insides, for the price it maybe worth upgrading some of the components for giggles (nice power supply, internals....). Plus a nicer case too. Hell you could combine this with a DIY preamp in a case and have a nice computer sound system for probably less than $100.

Ok, the little Tripath amp arrived today and I took a couple of initial shots of the innards.

The board is attached via two molded in standoffs which are then melted and three globs of glue to tie it to the case so I'm not ready just yet to rip the board out to photograph the component side.

The knob on the front panel is a combo on/off volume control.

Haven't really listened to it. Don't have any reference speakers at the moment so I just plugged it into my little JVCs to make sure it worked. It did.

Steve,
I take it that it uses a 3.5 mini stereo plug for the inputs (no RCA)? Have you tried it using AA batteries? I think this little guy might be my soultion to a portable testing rig for MLS, RTA, etc. !!!

Yes, one of the Tripath chips. You can see the component side through some ventilation slots that are between the two battery holders.

I don't want to pull the board out of this until I have a new chassis to put it in. Should work ok in one of my canary coffins. I'll see if I can have something worked out today.
