Been Tektronix user since 1967 and scopes 454, 485, 465, 465B, 475.
Since early 90s had 2465, 2465A and nos 2465B, 2467B.
In digital worked with Yokogawa in 1990s so had DL1540, 1740, DL7440.
Use the TEK 2465B for most analog troubleshooting and maintenance, the Yokogawa scopes have many fine averaging and calculating functions incl FFT.
The TEK are easy to maintain, need recapping and new NVRAM after many years, but parts and full serve]ice manuals and CAL procedures and CAL gear still available.
On tekScopes.groups.io many deep users, fixers and ex TEK folks who can give you a lot more info.
You could get a good 2456B for perhaps $300-600 on epay.
Avoid the older serial numbers and 2465 or 2465A versions, the B is the best.
LAST CRT scopes from TEK!
Bon chance,
Jon
