New Headphone Stereo Amplifier Kit DIY OpAmp Cmoy Amp - eBay (item 380096879676 end time Jan-15-09 04:18:55 PST)), but due to circumstances won't be able to build and use it. So, if anyone wants it let me know. I'm selling it for $12 + shipping.
Here are a few details:
"...Super powerful OpAmp (JRC Japan Radio 4556AD OpAmp) Headphone Amplifier
Needs assembly. Once assembled, you have super strong headphone amplifier.
You won't believe the volume this little amplifier puts out. Clean sounding too...
...The kit has everything you need...except the project box. Any Altoid(tm) or mint tin will work. You will also need a soldering iron and some solder."
Comes complete with a schematic and assembly drawing. Uses 2 9 Volt Batteries
Also...your choice of Yellow or Blue LED. Both are included. Only one is needed for the kit.
