You can make self oscillating class D with just comparators (LM311, LM319, TL3016) and optionally op-amps (for THD reduction).

The heart of the high performance class D amplifier in which I'm currently working (commercial project for PA) is just a comparator and a quad op-amp.

Also OUTPUT coil(s) too, alot of amplifiers failing or getting hot because improperly output coil(s) used.
