Dave repairs a classic Tektronix 400MHz 2465B oscilloscope that’s been sitting on the mailbag shelf for years.
Arguably the greatest analog oscilloscope ever made.
BONUS magic smoke escape!
Although it was repaired to a functional level, this is kinda Part 1, as not all functions were exercised and tested, and not all parts were refurbished.
