  1. Speaking of Walkman - I didn't have one of those oh no. I had an Aiwa unit with AM/FM tuner too.

  2. The problem with vacuum tubes was that they were power hungry and generated a ton of heat. Sure some transistors generate heat too. And the first transistor was what is called a point-contact transistor, and the Field Effect Transistor which was just a sandwich of NPN or PNP.
