Based on my past experiences, I spent at least two hours each day to read electronic servicing books and magazines. I have learned tips and information, which helped me to be more efficient and enhanced my knowledge about electronic servicing. I have benefited tremendously from reading these technical books and magazines. I am now a successful technician with a rapidly growing business, which specializes in repairing monitors and printers. I believe that you, too can achieve what your heart desires!

Part 5: Phosphor Type The fifth symbol gives phosphor designation. The letter X here corresponds to P22 for colour picture tubes. Colour monitor tubes can have any other single letter (excluding I, O, or W) to designate other phosphor type for various applications. For monochrome pictures, phosphor symbol is WW, corresponding to P4. Monochrome monitor tubes also can use WW or some other two-letter combination (excluding I and O).

Part 6: Integral neck components The sixth symbol is assigned only for tubes having integral neck components, such as deflection yoke. The specs are only apply to a particular tube manufacturer. The primary consideration here is winding inductance. The yoke coils have different sensitivity i.e. deflection per Amp in both horizontal and vertical.
