When I was in technical school I spent many evenings and weekends repairing
50s TV sets and never had a problem keeping away from the HV.
Then I spent 20 years working on solid state electronics, mostly audio. I
got quite used to using my fingers as signal tracers.
Finally I decided to work on one of the old TV sets. I was amazed at how hard
it was to keep my fingers out of the set. I kept wanting to touch a tube
socket to see if that would effect the signal.
Perhaps the more experience one has with modern electronics, the more
dangerous it might be for them to work on an old 500 series scope!
