Both B&K and Sencore made really well built units, though the general consensus seems to be towards the later built models. (Some people swear by Beltron. I have no experience with their units)

The B&K models 467 and 490(B) are generally regarded as the best models in the B&K lineup. The 470 and 480 being the single meter versions of the equivalent testers.

The Sencore CR70 is the equivalent to the B&K 467/90. The CR7000 is a fully digital tester to complete the icing on the cake.

Personally, the CR7000 is overpriced ($300+) and really doesn't offer much more over its counterparts, as is the 490 ($200+).

A CR70 or 467 will do everything you need to do without breaking the bank. Make sure it comes with adapters, as buying them individually can add up. (If you even find them) The 467 uses adapters 10 and 9 to test the 17HP4 and 21FDP4 respectfully. The CR70 uses the universal adapter (UA) and adapter 4 respectfully.

*side note* The universal adapter can be used to test most tubes if an adapter is missing.

Ultimately, a B&K 467 or CR70 is the best bang for your buck for general tube testing and rejuvenation. Both were designed to accommodate a wide variety of tubes and generally give a good indication of the tube's emmissions.

Hope this helped,
Zach
