https://stream.echo6.co/videos/watch/87b6c47e-ebdb-4b70-97b6-f28ac74216d7 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.
