Is there any way to make an audio amplifier from common household materials?


magnetic amplifiers old simple tech, believe used in pow camps(with restricted materials) during ww2. construction detailed @ http://www.sparkbangbuzz.com/mag-amp/mag... might useful.

web site has page on homemade thermonic valves (using flames rather vaccum). not quite old tech magnetic amplifiers again constructable @ home (if ok working higher voltage)

alternatively 555 timer ics still common in household electronics. can used construct amplifier too. schematic @ http://www.electronics-lab.com/blog/?tag...

i have rca mp3 player wired car stereo, @ full volume, not loud enough. assume need amplifier, on tight budget. wondering if there way can make amp common household materials.
