Me too, that's how I got the insight.
I resemble that remark...

I tend to like the older test equipment like others.
I remember when I was in tech school my electronics instructor and a couple of others went on a field trip to the GE electric motor plant in Hendersonville TN to visit a former student that was helping with donating some test equipment to the school. That was in the early 80's. Of course we got a tour of the factory and got to go in the anechoic chamber where they tested how noisy the motors were. One of the things we got was a Tektronix 545 scope along with several of the plug-in modules. That scope is a large and heavy beast. It worked fine for awhile, then the HV rectifier died. Unsure if we could find another tube type rectifier, so I came up with the idea of using a bunch of 1 Kv PIV diodes in series to replace the tube type rectifier. Took a bit of fiddling with getting the solder joints so there wasn't any corona discharge or arcing to ground, but the idea worked. Maybe too well since it had a bit more high voltage to the CRT than with the tube type rectifier.
Another thing we got from the visit was an HP frequency counter with the Nixie tube display. A 5245 I think? They are a large and heavy beast too.

The best you can do would be a cursory alignment. A proper Metrology lab would have the needed voltage and frequency standards. The old scope are just going to be ignored. Everything is digital and computer controlled these days.... Days of analog are pretty much gone.
My first scope in the Navy was a Tektronix 545.... Great scope....
