There is a very long thread in the Amp section about 2sc2879 transistors and what the absolute maximum amount of power is that they will produce.

Tom, W8JI a ham that has written a lot of stuff for the Ham radio community as well as being an engineer and designer of amplifiers for Ameritron took a single 2879 and mounted it in a test Jig on a copper plate, Tom's calculations showed it's possible to reach 300+ watts output deep in class C without exceeding the dissipation rating of the transistor.

 That is balls to the wall and no one in there right mind would want to operate them like that for any period of time, not to mention that the signal would be far from clean at that number.

 About 120/125 watts peak power is reasonable at 13.8 to 14 volts in a well designed amp if you want it to live well and run somewhat clean.
