Скачать или смотреть B+K Precision Model 470 CRT CATHODE RAY TUBE TESTER/REJUVENATOR - Overview

This video is an overview of the Dynascan Corporation (later: Maxtec International Corporation), (later again: B&K Precision Corporation) B+K (B&K) (BK) Precision Model 470 Cathode Ray Tube Tester/Rejuvenator (CRT Tester/Rejuvenator).

It seems over I guess 60 years of buy outs, mergers, model succession, there has been an extensive amount of brand alterations. And whilst B&K Precision Corporation discontinued the line on 1st May 2007 with the Model 490B it seems these testers are heralded as some of the most reliable of their respective category.

In this video I cover a Model 470 purchased from eBay 17th Feb 2022 for £122.01. It seems to be in relatively complete condition, including most if not all original paperwork and 7 CRT socket adapters. Adapters included: CR-3, CR-5, CR-15, CR-21, CR-23, CR-24, CR-25.

Shown in the video is a high-level overview of what I have bought, a basic cleaning process and general maintenance (replacing the plug and using Deoxit on some of the pots), reassembly and general demonstration of the unit as per the manual’s guidance.

As promised in the video I have uploaded all documentation to archive.org (except the setup chart as there are better newer resources for this). (Links further down)
