Depends on the load impedance for 8 ohms you should be able to get the magic 100W with +/-22v supply but for a 4 ohm load you should use +/-18v to get 100W
I would not run them for long at that level because the To220 package does not have the area to get rid of the heat easily!
One way around this is to build the "superbridge" in the TD2030A data sheet which has booster transistors that take some of the power dissipation.

Just found this application on the ST site (makers of the TDA2050)
Unfortunately it does not list that device but if you select TDA7265 which is approx 2 Tda2050's on the same chip but bigger area package you can get an idea of the dissipation problem

Application needs java to run
