Volume pots (what you really call the volume knob) vary WIDELY in their
linearity relative to power output. So, no, the relative position of your
volume control does NOT tell you how much power it's passing.

I am thinking about buying a new amp and would like to know how much
power I need. My current amp is rated at 25 watts and I never put the
volume knob past the 1/3 point and I never have problems playing music
LOUD enough. Is the power usage proportional to the volume knob
position, am I always using less than 12 watts?

TIA
