I'd agree that this Admiral would be a great one to start with. Straightforward.
This set probably uses a lot of black beauty caps. Often called bumble bees-they are marked with colored stripes, similiar to resistors, instead of having the values printed on them. For the longest time I mistook them for big resistors, and I don't think I'm the only one! Helpful to have the Sams when replacing them since they're not always easy to decode. You should save the old bb caps-people have been known to pay good money for them on ebay!

Yes, I was once one of those that thought bumblebee caps were resistors. When I was about 12, I found one of these caps blown apart in a radio. I took the cap to the local parts house and told the older man working there that I needed this resistor. He explained to me that the part was a capacitor and pointed out the foil.
As far as CRT testers, I use a B&K 480 from the '90's. With the right adapters, it will test most CRT's from the late '40's to the present. If you can't find a Beltron, look for a B&K 467, 470, 480, or 490. Try to stay away from anything before the 467. They will check the older tubes OK; but, their rejuvenate function often does more harm than good. My first CRT tester was a B&K 465 and I ruined more tubes (especially the color tubes) than I helped with that model.
