LM3876 amp info needed - Page 2

Years ago, I took a cheap 12V bridged output amp, drove it with square waves, which then drove a charge pump. A variation of that type of thing may be an option also.

I will look into a switched power supply. My electronics teacher said that maby I could look for a "voltage doubler". Might do that also.

Thanks for the help.

A voltage doubler needs an AC signal driving it, that's pretty much what subwo1 was referring to. It ends up being difficult to get a lot of power out of it.
