Parts needed

  • Transformer - input 240VAC output 12VDC
  • Bridge rectifier - single package or four diodes
  • Capacitor - high value - 12V
  • Voltage regulator 7805
  • Mounting board - high current rails

Parts in stock

  • Jug socket
  • Capacitor - low value microF - to reduce RF emissions from regulator
