How about Jan Fredriksson's AMP 3?
No problem sourcing components etc., and plenty of room for experimentation / modification.

if the amps arent too expensive i will think about it! its just a project fpr physics! i dont want to use a big psu or something else but i want to use it for my tv after the presentation in physics so the quality should be not the best but better than the panasonic, aiwa or phillips blinky systems ;-) i live in germany so i think its not easy to buy a pcb form the usa, isnt it? where can i get Jan Fredriksson's AMP 3?
i found amp 4... for 25€ inclusive components its a good deal! do i need a preampfiler or is a poti enough? what kind of poti should i use?

A 12V SLA battery with ~10,000-20,000uF reservoir caps, ~20k volume control pot, and it will not only beat the Aiwa and Philips, but the NADs, Rotels and many others 😉 . A preamp is better (cleaner bass, better body in the sound), but can always be added later.
One of my Amp3s is destined to be a booster amp for my son's Aiwa minicompo. I replaced the speakers with a small pair of DIY speakers, and someday the Amp3 with take the headphone signal from the Aiwa and feed the speakers. I tried this with the T-amp, and he loved the sound. With the Amp3, he will make his entry into "hi-end" minicompo!

If the source has a volume control (eg. Discman), you can skip the volume pot altogether.
Get an old Sony Discman; add a good low ESR cap at the battery supply terminals internally; connect to something like the Amp3, and you have a *killer* portable system. Bring it to a friend's house and hook to the $3k speakers and 😀 😀 😀
