Default tests to do on used oscilloscope?

In article ,
says...
One I built from new parts when I was 17 - way back in 1970.
Uses 5 tubes ( twin triode and triode pentode types ) plus is fully calibrated.


Well done. Me too, in the early 1960s, but it was from 2nd hand bits,
especially the VCR97 CRT. And definitely not calibrated! I still have
it, and it works just as badly as originally...
