VAC means either the voltage is direct or alternating
however, if it is connected to the mains, VAC means alternating
sorry, I can't remember how to differentiate them

VAC = alternating current voltage :)
Class AB:
It works like a Class A, being very faithful but mainly used in low power amplifications requiring precision and low noise (preamps, CD players, etc.) (increased conduction time of the transistors) and switches to Class B operation using 2 transistors in "push-pull": one to handle the positive half-cycle and the other the negative half-cycle of the signal. It has the advantage of heating much less.
