After a long hiatus (see parts 1, 2, and 3 on the original SCANALYZER), this classic instrument, with fifty-two vacuum tubes, is finally restored to its original 1950s glory, but not without the release of some additional magic smoke along the way.
I’ve actually used the signal generator in this video. It finally died a few years ago. Never used a 'scope quite as old as the 150A but even the newer analog 'scopes were horrifyingly awful to use compared to modern ones.
