Two Amp Power Supply

The Two Amp Power Supply circuit diagram.

This handy power supply has an output of 0v to 12v at 700mA with a transformer that is rated at 1-amp (such as M-2155) or 1.4amp for a transformer that is rated at 2-amp (such as M-2156). Your local electronics shop or model railway supply will have these or equivalent transformers. The mini pot mounted on the board has a scale to show the approximate output voltage and this can be replaced with a standard pot on the front of a case. You can also include an ammeter if you wish.
