This power supply can be implemented with a TIP32 providing an adjustable output at the 2k2 potentiometer or even 4k7 (wire). The transistor must be equipped with a heat radiator and the diodes can be 1N4002. A 9 or 12 V secondary transformer can be used to achieve a higher maximum output voltage. The circuit is from a 1970s publication.
