Hi

I want to build a nice little class AB that cun run off of wall-wart or maybe even batteries.

So what I was considering was building a tracking inverter that will invert the input voltage and track it on the negative. I'm struggling to find circuits/chips to do this, any pointers? Another solution is to just double the input voltage and then set the ground as the input positive rail, is that a clumsy way of doing it?

Just looking for advice, looking to run something class AB with 30W or so power output.

Cheers
