Information
                                    Introduction The Sencore CR70 “Beam Builder”™ Universal CRT Analyzer and Restorer is designed to test and restore any type of CRT (cathode ray tube). The tests analyze each type of possible electron gun failure to provide accurate information about the ability of the gun assembly to produce an electron beam with the correct specifications. This information helps you decide whether the CRT will continue to operate in the circuit, whether you should attempt to improve its condition with the CR70 “Beam Builder" functions, or whether it should be replaced. The beam building functions provide five different levels of cathode improvement, providing the correct type of restoration or rejuvenation needed to improve most defective CRTs with the safest cathode recovery methods possible. You use the test results to guide you through the beam building steps. Features The CR70 tests each gun and each element individually, using dynamic tests which simulate the CRT in actual operation. The tests confirm that there are no inter- element shorts, that each gun has the correct dynamic range (range of cathode current between darkest and brightest display) and that each gun has enough emission level to produce an acceptable image on the CRT screen. Color reproduction problems are readily identified with a patented color tracking test, which compares the emission levels of all three electron guns of a color CRT, or the three individual CRTs of a three-tube projection system, to confirm the three colors can be properly balanced against each other. The CR70 provides five types of cathode recovery to allow you to use enough current to do the job effectively, without applying more than would be safe for a particular type of CRT failure. The CR70 meter monitors the amount of restoring current, allowing you to control the results. The CR70 operates on only one gun of a color CRT at a time allowing the beam building action for each gun. The design of the CR70 allows the use of the fewest number of adapter sockets possible. Because of its unique design, the CR70 is virtually obsolete proof. Unlike other CRT testers, the CR70 requires only one adapter socket for each type of CRT base. Setup switches let you compensate for different wiring configurations for a single style of socket. The setup swatches relate directly to the pins of the CRT, allowing a schematic to be used to determine the testing information for a CRT that is not listed in the CR70 setup book
