B&K CRT tester

That's a model 465 from the '60's and I'd leave it alone. The rejuvenate function on these models will usually do more harm than good and these older testers often do not have the sockets for the newer tubes. My first CRT tester was this exact model. It was given to me by a TV shop in the early '90's because it was obsolete. At the time, it was OK because most of the CRT's I found were older delta gun color tubes and older B&W tubes. I finished off several weak CRT's with it's rejuvenate function. I believe B&K made an adapter that would allow the 465 to be used with modern adapters; but, since the rejuvenate function isn't the best, I'd move on to a newer model.

I'd look for a B&K 467, 470, 480, or 490 tester. These are newer and have a much better rejuvenate function. Also, sockets are available for most any CRT. These cost several hundred $ when new; but, can often be bought on epay for a reasonable price. I look for them to get even cheaper as the CRT becomes more obsolete.

I've got a 480 with most of the sockets. I have rejuvenated many tubes with it with good results.
