Or perhaps it should have been stated as usable watts? But if that transistor has reached it's maximum current handling ability at less than maximum collector dissipation, it's still reached it's maximum ability, hasn't it? So...

Of course Doc, but the point is the maximum output power is way more then 167 watts per transistor and you can reach 252 watts output without exceeding maximum dissipation or collector current on the 2SC2879.
