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.

The previous LCD repair didn’t last very long. Redux time.
Installing a new 240×64 LCD module in the PM300 Power Analyser wasn’t exactly a walk in the park.

Are you getting ripped off with Energizer and Duracell D cell NiMH rechargeable batteries?
Why is a D cell NiMh the same capacity or lower than the smaller C or even AA cell?
Teardown time!
