The manual for the CRT Adapter Model CR-12 provides instructions for setting up and operating the adapter with B & K-Precision Models 467 and 470 CRT Tester/Restorers, specifically for testing special CRTs with a common cathode terminal. It details the necessary switch settings and procedures for measuring beam current and testing emission levels for each color gun, as well as instructions for performing focus tests and using the restore/balance functions.
Manual Overview
The Bk MANUAL for the CRT Adapter Model CR-12 provides instructions for technicians using B & K-Precision Models 467 and 470 CRT Tester/Restorers. The CR-12 is essential for testing specific CRTs with a common cathode terminal, such as the G.E. 11SP22 and LL WP22, by enabling independent measurement of beam current in each color gun. For Model 467, the CR-12 is connected between the CRT and the tester. The switch on the CR-12 is used to select the color gun being tested, with separate settings for RED, GREEN, and BLUE. Technicians follow the 467 testing procedure to set heater, G1, and G2 cutoff voltages for each color. The emission levels of all three guns can be compared by setting the function switch to EMISSION. For Model 470, the CR-12 is also connected between the CRT and the tester, ensuring that the 470 GUN SELECTOR switch matches the CR-12 switch for accurate readings. The manual emphasizes the importance of correct switch settings for RESTORE/BALANCE functions.
Quick Issues Covered
- Diagnose CRT beam current with CR-12 adapter on Models 467/470.
- Adjust G2 cutoff voltages using CR-12 switch for color guns.
- Ensure CR-12 and 470 gun selector match for accurate readings.
Overview
Model CR-12 is a CRT adapter designed for use with B & K-Precision Models 467 and 470 CRT TESTER/RESTORERS. It is necessary for testing a specific family of CRTs with a common cathode terminal, such as the G.E. 11SP22 and LL WP22. The adapter allows for independent measurement of beam current in each of the three color guns, providing accurate quality measurements. The manual provides instructions for using the CR-12 with both Model 467 and Model 470, detailing the switch settings and procedures required for testing and restoring the CRTs.

Installation / Setup
The installation/setup of the Model CR-12 CRT adapter involves connecting it between the CRT under test and either the B & K-Precision Model 467 or 470 CRT Tester/Restorers. For Model 467, the CR-12 switch is used to select the color gun being tested, and the testing procedure involves setting heater, G1, and G2 cutoff voltages for each color. Emission levels can be compared by rotating the CR-12 switch. For Model 470, it is important that the 470 GUN SELECTOR switch and the CR-12 switch are set to the same color gun position for accurate readings.
Operation
The Model CR-12 CRT adapter is used with B & K-Precision Models 467 and 470 CRT Tester/Restorers to test special CRTs with a common cathode terminal. For Model 467, connect the CR-12 between the CRT and the tester, set the CR-12 switch to the desired color (RED, GREEN, or BLUE), and follow the 467 testing procedure to set voltages and compare emission levels. For Model 470, ensure the CR-12 switch and the 470 GUN SELECTOR switch are set to the same color gun position for accurate readings.
