They are used prirnarily 2N301 in class A power-output stages and E B class B push-pull amplifier stages in 2N301A automobile radio receivers and com- munications equipment. These types have a high de forward current-transfer ratio which helps to minimize distortion in applications requiring high power out- puts at low supply voltages.
