Recommend a CRT Tester/Rejuvenator and Tube Tester

[CoogarXR]

Hey fellas,

I wonder if you guys could recommend a good CRT Tester/Rejuvenator that I could find on ebay or whatever. I am also looking for a tube tester. I am starting off working on these two 1951 Zenith portholes, but I may get into tube audio some day too. I would like something to be able to test these two CRTs and and a variety of TV and audio tubes. There are so many choices, and with little tube knowledge, I don't know what I am looking at .

So-what do you pros recommend as a good, but inexpensive tube tester, and separately, a CRT tester/rejuvenator?

Thanks
