What all Rejuvenators will work?

[minniescar]

 By reading here i can tell that b & k 467 Rejuvenator seems to be the prefered and that a b & k 466 can work if a special adapter is made, but what about other manufactures models. I mean where is the cut off point that they are to old of a model to use , for instance i see a heathkit on ebay going pretty cheap with a manual and instructions but what models would be to old. Anyone got a list of basically what Rejuvenators are to old?

I am only familiar with the B & K product line.

I do know that Sencore, aside from also being way way overpriced, only supports their current model the CR7000. For the prices they charge, their support is awful. If the product is over 5 years old you're out of luck as they won't support it. They'll give you the old line, "Did we make that?"

Heath and Heathkit products are excellent, but I'm just not familiar with their rejuvenators.
