One interesting thing about a CRT based scope, especially Tek, right up to the time that CRT's became obsolete, the technology was perfected after years and years of R&D.
This meant that the latter generations of CRT's were fantastic, with small diameter sharply focused beams with negligible geometry errors and wonderful corner focus. Also very high EHT voltages with high beam energy, giving great brightness. They only went obsolete for two reasons, size (depth specifically) and cost, as they became the most expensive component in the scope.
CRT's of this advanced character (like the ones in a Tek 2465B scope for example) in the last generations of Tek scopes can only be described as "Masterpieces of Electron Optics " and I assure everyone that when you inspect one of these CRT's and have a look at their refined gun structure, glasswork, metallury etc, it is nothing short of miraculous.
But, they were almost too good to have in a brave new world of throw away equipment. They totally outclass, by a country mile, any digital flat screen. It is possible to see details in waveforms on a CRT that are that are not possible to see on a digital display screen of the resolution used in most digital scopes. This is because the CRT's beam geometry (thickness) and brightness is altered by the beam velocity. Though there have been some attempts to try to replicate this effect with a high res pixel based screen. Combine this with the types of wideband analog ASIC IC's that Tek designed to support their CRT's, the result is amazing and in the Analog Scope arena one could argue that their equivalent "sample rate" if they were digital, was about 1/the Planck interval.
In the digital scope area I still prefer a digital scope with a CRT than a flat screen of any type. The OP's scope looks great to me, as does the HP scope posted above.
So I can see why people get excited over CRT based scopes of any kind, I know I do. And, now they are a non-renewable resource, so it makes them even more valuable.
