The major component of deflection coil is copper, which price was, from the beginning of 2004 to the first days of March 2004, rapidly increased by 30%.
Because these new displays employ pictures tubes of significantly reduced depth, the angle through which the electron beam must be deflected during each horizontal scan is increased from 110 degrees to typically 124 degrees, which places stringent new demands on the bipolar power transistors that control the flow of current through the horizontal deflection coils.
This is due to the lack of large deflection coils required by tubes.
