Hey all,
I think I know the answer to this and I may be in the market for one of these soon. But does anyone want to chime in on their opinion of what the best Tube rejuvenator is and why. I ask because I think I might need one, and a friend recently said he had heard Sencore was the brand to get. I had always heard B&K was the best. So anyone have any opinions of the best brands and models. My money was on B&K 490 or 467. So, educate me.
 
The Sencore models CR70 and CR7000 are the top-of-the-line and sold new for quite a bit of money.

B & K Precision models 467 is old, but can be purchased reasonably priced. The 490 model was issued is two versions which use different adapters. The 490A (also known as the plain 490) is the earlier version which uses the standard CR series adapters like other previous B & K models. The 490-B is the later version and the circuitry is totally different internally (computer controlled) and uses the CA series adapters (different than CR series). The 490-B was B & K's answer to Sencore's CR7000 and at half the price of a Sencore.
 
I personally like the B&K 470 or 480. 470 can be had for about $50 on ebay and hopefully it will have the CR23 adapter. Very simple to use.
 
BK 467 seems to be easier to use than the 470. Basically the same as the 490...
 
I'm not all that familiar with the Sencores. Do they use custom plugs/adapters like the B&Ks, or do they have use a neck plug with leads that you have to put in the proper place. Never seen any plugs for the Sencores, but I've seen plenty for the B&Ks. And if the Sencores do use custom plugs, are they still readily available. And I know they all do the same job. Does the Sencore just do the job better?

I got an affordable Sencore CR70 when all he BKs seemed to be around $150 and over. they do use different adapters and you find much more info about the BK on the web. The good thing about the sencore is I got all the adapters including the "universal". I did dislike the fact that I had to use the universal for my Sanyo EZ. I had hoped it would have rated an adapter. Happy with my sencore in all. And they do have a website to look up obscure tubes you find at thrift stores.

The CR70s don't use custom plugs/adapters so to speak. There is, or should be, a selection of adapters stored in lid. They are form factor based as opposed to pin out based like the B&K design. The guide book tells you which adapter to use to fit the neck of the tube. It also tells you how to set up the dials on the unit to "program" it for the correct pin out. Its like 4 or 5 settings, no real big deal. The adapters are 2 sided. 1/2 are the same physical adapter, 3/4, etc. "Classic" arcade monitors use the 3 side of 3/4. Not sure about the Sanyo comment. Its been a while since I have done one but I seem to recall them being the same as a "Classic" tube. As to the universal. I terminates in clips that you have to attach to the appropriate pin. It's used on odd ball cases where there is not a pre-made adapter to fit. I have had to use it a very few times. Mainly off the wall monitors and the good old Matsushita in some Ataris.
