This information was kindly provided by Ken Layton.  It is an excerpt of various posts regarding the B&K 467 rejuvenator.  This unit is an excellent addition to the serious game restoration tool kit; it can add years of life to faded dark or blurry picture tubes (CRTs).  It will NOT however remove screen burn.

73-300    497-022-0595 B&K Adapter guidebook (shows what tubes use what adapters). This is also available to download at www.ionpool.net

The above adapters are used with models 467, 470, 480, and 490 (but not the 490-B which uses completely different adapters).

The manufacturer, B & K Precision (www.bkprecision.com) still supports this piece of test equipment even though it was manufactured 30 years ago. If you send the unit back to the factory they will test/repair/recalibrate for you. A common failure is the "Push to remove shorts" pushbutton switch assembly in which the switch internal contacts wear out and shipping it back to the facture for repair is a good idea.

I have been told that the factory service department will manufacture
whatever socket adapter (s) you need for any adapter number that has been discontinued but you must specifically tell them that. Adapter # CR-30 has been discontinued and as an example that's the one you need. Just tell the factory service department you want them to make a CR-30 for you. Cost is $50.
