Do class A amps draw power even when turned off?


I have a Pathos TT integrated amp (class A). The manual said it draws 300 watts even when there is no signal running thru it. Does this mean that it is drawing 300 watts even when I have it turned off, or only when it is turned on regardless of whether or not it's playing music???

If it still draws 300 watts of power when turned off, I guess there is no harm in un-plugging it?

Zaikesman, that's very interesting. I'm not questioning your statement but am wondering if you can site a source for it. I've noticed this phenomenon with an amp I have that claims to run class A for first fifteen watts. I always attributed the cooler amp after playing music to the fact that the amp is sometimes running A/B. Thanks.
Zaiksman, thanks for that info. Yes it does make sense, even without the engine analogy.
