A friend just bought an almost brand-spanking new B & K 490 rejuvenator. I've decided to document it since there is little information out there about it. First of all there are TWO distinct 490 models: the first one has analog meters and the last version is CPU controlled and has a completely different layout and different operating instructions. The analog one is called the "plain" 490 or sometimes known as the "490A". This model manufactured from 1988 through 2002. This is the one I will be discussing here. The digital CPU controlled one is called the 490-B and uses completely different adapters than all previous models. That model was made from 2003 to 2007.
My friend was lucky in the fact this plain 490 came with all of it's original paperwork & manuals. I will get around to scanning it all when I can. It did include a schematic and parts list. I took it out of it's case and guess what? It is exactly the same circuit board as the model 467. It even operates the same as a 467.
