Good Morning!
Hmmm...First TV...First stereo...
I remember my first, my very own cassette/radio player - nine-years old, living in Seattle, Radio Shack - went through "C" batteries very fast.
I remember my first CD player - 16 years old, living in Arlington, VA, Sony, 5-disc changer. I still have it, but the laser needs to be aligned, and since the repair would cost as much as a new one...
As for a TV... I don't think I've bought one for myself. My parents had one of those big console deals, black & white, that I loved. ?? And my parents also had a Panasonic record/cassette/radio system that I more or less made my own when we lived in Seattle. I even had it when I was in college.
