>what's stopping me from yoinking the audio amplifier IC out of some old stereo system .... and using it as an inverter

if you yank the chip out, you then have to replace all the circuitry (and power supply) you've discarded.
that's dumb: better to keep the amp intact, and just feed in the waveform you like.
i've done this myself, using a 500W amp to drive incandescent lamps, to create a zero-work ''color organ''.
