Whitesel) Distribution: na Organization: California Institute of Technology Lines: 11 Looks like you have two easy (?) choices: increase the resistor value so there will be less current and therefore less heat. get another resistor/transistor pair and run them in parallel so each only dissapates half the power (you'll have to fix the resistor values) and therefore half the heat.
