Customers should consider CGS14 from Ken Stone as a suitable alternative

This design provides a low-cost solution that uses standard fixed-voltage regulators. Purists may wish to use a precision voltage regulator design.

The unit has the following features:-

Output voltages: +15V, -15V
Output current: in excess of 500mA per rail
Current limiting and thermal shutdown protection

Panel controls:

None. Optional LED status indicators for +15V and -15V.

Connectors:

3 x Internal buss connectors with +15V, Analog Ground, Digital Ground and -15V connections

By substituting other members from the 78xx/79xx family you can generate a variety of power supply outputs.

To complete the module you will need to connect to a mains transformer. Please refer to this document for some suggestions.

! WARNING !
Readers should be aware that constructing this circuit involves working with mains power components. Readers are advised that they should not attempt this module unless they are fully aware of the various safety requirements relating to this type of circuitry. There are several good ready-made designs that the reader should consider if there is any doubt or concern regarding the building and use of this module.
