Bald Engineer's e14 Blog yes my 465B is still ticking.. never loses a beat. the only thing that broke was one of the four feet, they also hold the cord. I have to print 4 more of them but the printer in the library is still a no-no covid.

Great choice for a teardown. The 465 has to be the scope that most epitomized the genre in the last century. The scope that set the standard that everyone else wished they could match. The most popular workhorse instrument - because of its great performance.

That's about the only reason I could think the analog amplifier board would have simple logic ICs on it.

What does the schematic show? You should be able to find one easily enough - I've got an old Tek 2215 (nothing like as nice as the 465, but smaller and more portable) and the manual that came with it has all the circuits in it.

I've never used an actual Tek 465 but, curiously, I would be able to operate one with my eyes closed. Back in the late 1980s I worked for a company making TV broadcast equipment and they had some Kikusui 'scopes that were a direct copy. To see short glitches, we'd often use the 'scope with a hood over the screen, so you were operating the controls blind. The front panel layout was beautiful for that. With the different shapes and sizes of control and the placements with the input controls operated with the left hand and the timebase and trigger with the right it was superb.

Good luck with getting it going. You should manage ok unless there's something fundamentally wrong with the tube or one of the proprietory chips - if the worst comes to the worst, you could look for another non-working one and you'd probably get a good one out of the two.
