Features of the Model 490 B&K PRECISION’s patented TriDynamic (tm) test method lets you see the performance of each gun on its own meter — simultaneously! The 490 measures only beam current that actually passes through the G1 aperture to the screen. All three guns of a color picture tube are tested in sequence 20 times per second. Because all three guns are tested simultaneously, leakage between the elements of different guns is pinpointed immediately. Cathode-to cathode leakage, once virtually impossible to diagnose, is displayed as positively as common G1-to-cathode and cathode-to-heater leakage. |
Features of the Model 480 A single large meter with multicolor scales is featured for accurate display of tube condition. |

Special Features of Models 480 & 490
Positive Good-Bad Tests: Unlike other testers and restorers, these models give you definite "yes or no" answers to tube condition. Automatic Restoration Timing The cathode of the individual tube governs restoration duration, so you can’t possibly make a costly timing error that will cause cathode stripping. Heater voltage is supplied to the cathode. A larger cathode automatically allows more current to flow longer than a smaller one. You Can Guarantee Restoration. B&K PRECISION has found that more than 95% of CRTs will function as well as new tubes after restoration. That’s why they think you can profitably guarantee each restoration for up to two years with 100% of the restoration fee creditable toward a new CRT during that period. Rugged Case Design Both models feature a rugged molded case with sturdy metal frame. With easy-carry handle, the 480 and 490 are ideal for field service. CRT adapters stow away handily inside the case lid.
