As a kid, the LM383 had particular appeal: it was the highest-power amp chip available that ran off a 'safe' voltage. I didn't need to do any mains wiring.

I was forever trying to find enough old car batteries to get more volts when I was a kid for precisely this reason.

That was until I nearly burned the shed down charging one up. I was confined to alkalines then. Boo hiss.
