| This blackout brought back to mind a dumb question I have long meant to ask. On the back of an NV-400, for example, it says the power consumption is 600 watts, (if I recall correctly). If it is turned on but you're not playing, does it still take 600 watts, even though it's not actually amplifying anything? |

Think of an automobile engine rated 300HP when it is idling. Probably not even one HP at that point. Such is the case with an amp when it is just turned on and nothing is being played through it.

| Thanks, gents. I think I'll play in stereo today, Classic 50-410 on the right, NV-400 on the left, fed by the Boss SE-70. (But not loud, and no air conditioner). |

On a NV400, that power figure is most likely when the amp is being run near or at full power. If the amp just idling, it's probably just a few watts. They run pretty cool. If it was a "Class A" amp then it would be at full power all the time no matter whether it was making sound or not.
