    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. :)
