The manual for B&K Precision covers the wiring scheme and assembly instructions for connecting CRT components, including detailed specifications for pin configurations and keyway dimensions. It also provides information on tube heater types and voltages, and recommends subscribing to a chart mailing service for updates on new CRT types.
Manual Overview
The Bk MANUAL provides detailed guidance for technicians working with B & K-Precision models 467, 470, 480, and 490. It includes a wiring scheme for CRT assembly, specifying pin configurations and color codes for proper connections. Troubleshooting involves checking the wiring and ensuring correct pin connections, particularly focusing on the nylon receptacle and associated pin numbers. Error diagnostics are primarily based on verifying the integrity of these connections and ensuring that the tube heater voltage is consistently at 6.3 volts for various tube types. Calibration and adjustments are not explicitly detailed, but maintaining accurate wiring and voltage levels is crucial for proper operation. Board-level guidance is limited to ensuring compatibility with the specified CRT dimensions and maintaining the integrity of keyway measurements. Technicians are encouraged to subscribe to the B & K-Precision chart mailing service for updates on new CRT types and to keep their setup charts current. For further assistance or to subscribe, technicians can contact the Factory Service Operations at Maxtec International Corporation in Chicago.
