Drive Transistor Test

Test each of the transistors Q1-Q4 or Q1-Q8. The plastic screw insulator is usually a
good indicator that the transistor is shorted if it is melted. The screws that secure the
transistors to the heat sink should be fairly tight. The insulating strip underneath of the
transistors should not have any holes in it besides the screw hole.
