Default Aleph X spreadsheet

You can figure the power with this easy spreadsheet. Here is the link http://www.diyaudio.com/forums/showt...066#post101066

I tried, but then there is another spreadsheet too. How much power can a single irpf244 handle , in terms of heat ? I just haven't seen anyone post final results. I am trying to get an idea if its worth it to build a pair or not on top of the pair of aleph 2s that I am building. My speakers aren't that efficient, if i could get about 50 watts per channel w/o adding more output devices then i'll go ahead and build a pair

I have taken IRFP240's to 50 watts continuous dissipation
and quite hot without failure, but I would not do it in
production quantities. 25 watts is my usual limit, but some
of our stuff runs at half of that.
