Abstract
A line scanning or horizontal deflection circuit for a television receiver including a first scanning thyristor controlled by means of a commutating circuit comprising a second thyristor an inductance and a capacitive circuit, fed from a source which is connected to the scanning circuit by means of a further inductance. According to the invention, the gating signal of the first thyristor is derived from the signal available between the inductance and the capacitive network being taken at an output of the line.
