Abstract: To decrease the internal resistance of a transformer operable as a television line transformer of the "diode-split" type, the secondary winding sections are matched to each other and to the frequency of operation of the transformer in such a manner that the current in the respective sections will flow at respectively different instants of time; in a preferred form, the winding sections, on the average, are tuned to a harmonic of the frequency of the signal applied to the primary and are positioned on winding forms or holders such that the distance between the bottom wall of the primary and the bottom wall of the secondary is constant over the entire length of the windings. Preferably, the tuning of the respective winding sections is effected by matching of the primary winding to the secondary within the region of the secondary winding sections.

Abstract: To permit use of a circuit in which the energy derived during horizontal flyback is used to control vertical deflection, without damage to the vertical deflection system upon vertical flyback, the vertical deflection output stage is dimensioned to have a time constant which is less, preferably about half, of the time constant of the sawtooth wave generator controlling vertical deflection. The vertical deflection output stage forms, in essence, a parallel oscillatory circuit which, to provide the lesser time constant, is damped.

Abstract: A saw-tooth wave generator including thyristors is provided in the vertical deflection circuit, the thyristors controlling charging and re-charging of a charge capacitor. A portion of the energy contained in the line retrace and delivered from the horizontal output stage is used in order to provide current for the vertical deflection coil. In order to prevent spurious or erroneous operation of the thyristors, an oppositely poled bias voltage is applied to the gates of the thyristors during the pauses or intervals of triggering of the thyristors, the bias voltage being derived externally or directly from the thyristor control circuit, for example by utilizing the inductive reverse-polarity kick of an inductance connecting the thyristor gate to its control circuit, by a charge-reverse re-charge circuit of a capacitor, or the like.
