Hello Steve,
I have a Tektronix 2235 and enjoy using it.? I used to have TWO until the CRT died in one of them.? After a week of searching, I concluded NEW/unused replacement CRT's for that instrument no longer exist and the couple of USED tubes I found cost as much as a new 'scope.
You need an oscilloscope to look at waveform time features such as distortion, amplitude, and time relationships.??
If I were buying a 'scope now, I would definitely choose one of the newer digital devices.? Hope this helps answer your question.
