Boosting an op amp's output current

Attached are two videos describing how to boost the output current of an op amp.

The first video presents a simple Class-B amplifier follower stage. It suffers from crossover distortion but may meet your needs for non-critical applications. The second video presents a circuit with significantly improved performance.

Please let me know if videos such as this are useful.

Also, are there any video topics that you would like to see.
