摘要： A cathode ray tube assembly has a circuit arrangement to connect the heater R1 of a cathode ray tube to an associated D.C. supply, (via terminals 12 and 13), and the circuit arrangement also includes at least one component, such as two components comprising astigmatism correction coils 10, to be energized by the D.C. supply, and a matrix of assymetrical conducting devices, for example, a diode bridge D1, D2, D3 and D4, arranged to ensure that the current flow through each of said at least one component individually is in one predetermined direction, irrespective of the direction of the flow of current from the D.C. supply.
