 		 #173050 - probably still too weak ...
Responding to: Ap Charles's previous message
He wants to source a total of 330 mA. I'd guess his power op-amp needs to be able to source/sink at least twice that, and at considerable speed. There is a power/performance tradeoff, though, as, with more power, he can rely more on bypass members to keep the pseudo-GND stabile.
