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.

DO NOT ask for personal advice on something, post it in the EEVblog forum
I get over 80,000 video views *each day* and that means a *lot* of email asking for advice, I simply can't keep up.
So I will no longer answer such emails as a rule, sorry.
I read ALL email, and try to read all Youtube comments, but please don't be offended if I don't have time to reply.
I don't read or respond to ANY private messages on youtube.
