[Boatanchors] Excellent YouTube video on restoring a Precision 612 Tube tester

[Bob Groh]

I was cleaning up the office today and in the process of digging up data on
my Precision Apparatus 612 tube tester, I found an excellent YouTube
presentation on the subject.  Very well written and the gentleman even
tears apart the meter and rebuilds it!  Yeah, I am impressed!

Highly recommended
