A capacitor Retrace Timing Capacitor or series of capacitors to provide redundancy is used to slow the collapse of the magnetic field.
Purity and convergence problems can occur at the same time, in the same or different areas of the screen or both over the whole screen, and either uniformly or to greater or lesser degrees over different parts of the screen.
Tuning would be adjusted until the width of a radial shadow was minimized.
During normal operation the shadow mask is heated to around 80-90 °C.
Increasing the length and proximity between plates in a pair can also increase the deflection angle.
A mental break also helps you stay focused in the moment when trading because your mind is aware that you will have time to look back on your previous trade decisions in the future.
