  1. Vacuum tubes.

  2. Ah, fixing the TV. Use to see these at Walgreens along with the TV Tube tester machine.

  3. Yes, well done to both of you.

    Ah, the good ole’ days. I remember them fondly when working on a 30 year old nuke sub when i was young and stupid. I had to troubleshoot and repair the boat’s radar more than a few times, often the problem was a bad tube. A lot of times the troubleshooting was very easy, rack out the assembly while it was energized and find the tube that was dark. :)
