I've had a few B&K 465s, and they are OK but the rejuvenate function is a bit primitive and more dangerous than the system in the newer 467 & 470. Also the 465 may or may not have any factory-issue sockets newer than for 1970s CRTs.
I've always liked the B&K 467 the best. It has 3 separate meters, so you can see how quickly they fall off in the life test (how long the guns keep emitting after you kill the filaments). In all the other B&K models, you have to do the life test separately for each gun, and rely on memory and a stopwatch. The B&K 467 & 470 both use the same adaptors, and new ones are available for new model CRTs.
The 470 is also good, but only 1 meter. Great for B&W of course. The 467 & 470 all left the factory with a full set of sockets that cover most every CRT from 1946 thru early 80s; even socket 9 for Predictas, and socket 5 for small Trinitrons. And the sockets for all the newer tubes are still made, and most can be had on eBay pretty easy.
None of these, however, have sockets for 7JP4, or 15GP22/19VP22. You can get a B&K universal one with clip leads and special instructions. That's how I did the projection CRTs of the 90s and 2000s, and with a bit of study, all other CRTs in history I suppose.
