Ken,
I only serviced the 4xx series of scopes.
We had a different technician for each series of scopes.
And I also serviced all of the Tektronix computer peripherals (terminals,
printers, scanners and desktop computers).
Sure wish I could remember just half of what I knew back then! ;-)

I did not work for Tektronix. I worked for an independent calibration lab
called "Intertyme Metrology Laboratory." I serviced a lot of Tek 547, 544,
535, and various plug-ins for them like 1A4, 1A2 and other specialty
vertical plug-ins. 465, 485. There was also a Tek scope that IBM had a lot
of, I don't remember the number. It was built in the style of a 547, but a
bit smaller and had plug-ins for both vertical and horizontal, a rectangular
CRT. I worked on some 7400 series scopes too.
Also some HP scopes, 182 C. I did not like Hewlett Packard o'scopes very
much. Nothing could compare to a Tektronix scope. HP for signal generators,
Tek for scopes would be my preference.
