Upgrade from 2465 to 2467? You probably DON'T want to do that. The 2465 is a direct view CRT. The 2467 is an image intensifier tube with a smaller screen size. If you have to view low rep-rate events at very high sweep speeds, the 2467 is better, but for most general scoping, it is a royal pain. If you turn the brightness up, the scope shuts down after a couple minutes to save the tube.
If you really need to see low rep-rate events, get a digital scope. WAYYYY better than the 2467 for about a dozen reasons. I have a 2465, it is a pretty good scope, and about the best analog CRT scope around. (A and B suffixes have a bit higher bandwidth.) The 2467 is the same basic scope with the microchannel plate intensifier, and as I mention above, it is a pain, and was only useful before digital storage scopes came out. Now, it is just obsolete.
