Tearing Down A Heavy Oscilloscope

A YouTuber's teardown of a 1960s Tektronix 545A oscilloscope is covered, highlighting its nearly 70-pound mainframe design, 75 vacuum tubes in the main unit plus six more in its vertical plugin, and roughly 500 watts of power draw. The piece touches on quirks like ceramic solder points requiring silver solder for repairs and the challenges of restoring the old graticule, with the restoration still a work in progress.
