I used one from 1973 or so until 1995. Great scope...on 8 hours a day

to matter...and I burned out a 50 ohm input termination once and some
indicator bulbs. I could see a single 3 ns pulse when I was looking
for a digital design startup problem if I set the single sweep, pull
down the shade and turn of the ceiling lights at the lab...put my face
into the screen. I had a storage scope (466 I think) but the 485
worked too well to bother. As far as I know it is still doing fine. I
didn't care for HP scopes. Not enough anode voltage to see that single
sweep pulse if needed.
My HP 1805 'scope has a 26kV accelerator.
It's a 350 MHz scope and Tek was always conservative with their
ratings.
