Abstract: A line output circuit has a transistor (TR) whose collector is connected through the primary winding (P) of a transformer (T) to a direct voltage supply terminal (2), the secondary winding (S) of the transformer (T) being connected through a diode (D1) to a terminal (3) at which an EHT supply appears. A diode (D2) shunts the collector-emitter path of transistor (TR) to provide a path for negative going sawtooth current. Two serially connected flyback capacitors (Cf1, Cf2) also shunt the transistor (TR), one capacitor (Cf2) being shunted by a switch (S1). The series arrangement of a linearity correction inductor (L1), a deflection coil (Ly), a further inductor (L2) and a trace capacitor (Ct1) also shunt the transistor (TR), the inductor (L2) and trace capacitor (Ct1) also being shunted by the series arrangement of a further trace capacitor (Ct2), a linearity correction resistor (R) and a switch (S2).
