Class A Amp owners, Whats your power bill?


I was curious to see how much a cost in power a month it went up when you bought a high powered Class A Amplifier. Also what is your impedance?

I cant help but think of Krell KSA-100's for about a G that would be great for winter time (Not so great for summer). And nows the time to buy one whn some one doesnt want to deal with the heat issues anymore (Hopefully)

Any way I figure it draws 800 +/- minus watts at IDLE! how much power you think I am pulling if I run it at a mostly 4 Ohm load when playing reasonably loud?

Thanks a million

It will be pulling 7.27 amps at idle, I can see the wheel spinning!!! The 25 watt lightbulb draws 0.23 amps.

Hardly any difference.

My Pass XA.5's draw 600 watts from the wall. At my 13 cents per kwh, it costs me less than a dime an hour to run them. Now, if I left them on 24/7 it would add about $70 a month to my elec bill (more in the summer because I would have the AC on more to help with the heat).

One thing that I like about Nelsons newer design is the standby switch. Only draws a few watts and no heat. The caps are kept fully charged so when I do flip them on it only takes about an hour to get up "heat" and they sound pretty nice while doing so. Electric co hates Nelson :-).
Joule Electra VZN-100's put a $30 shelf on my electric bill the month they showed up. I look at it this way, they serve to offset the heating bill for the winter. My basement is never cold and I don't have to turn the heat on down there. I can't use them when it is much past 70 out. I put one of those kill-a-watt things on it, draw was something like 11 amps. I also tried plugging them into powerstrip with my other equipment when diagnosing a ground loop issue. The powerstrip blew almost immediately. They do draw the power.

And remember, if you are making heat with your amp while cooling your house with AC, every penny in electricity that your amp uses will cost you another penny on the AC bill*the inefficiency of your AC.
