12 V x 3.5 A Power Supply (CB1215E)

  The diagram of this source appeared in a 1982 American publication, drawing attention to its different configuration. The circuit can be with more modern transistors, which we already give in our drawing version. The rectifier diodes can be 1N5402 or 1N5404. The 2N3055 must be mounted on an excellent heat radiator. The transformer must have a 15 V winding with 3.5 A.
