This solution has a disadvantage! The power-parallel-pas-transistor is not saved with overtemperature. You have the problem with second breakdown. Not so with parallelconnecting of any LM317. If you will create a circuit with additional power-transistor you must proof the temperatur with an additional circuit or you make the cooler very large calculated as worstcase. Bye Thomas
