List of components |

| Resistance and potentiometers: | Capacitores: | Semiconductors: | Several: |
|
- R1 - Potentiometer 50K |
- C1 - 3300 uF, 25V electrolytic (filter) |
- D1, D2 - rectifying Diodes 1N5402 - Q1 - Transistor BD137 |
- T1 - Transf. of 220V with ESA of 16 + 16V - 1 thermal Dissipater. |
This V is the design of a variable source from 0 to 15, without protection against short circuits. The unique recommendations important to consider are:
* The Q2 transistor must be placed on a good thermal dissipater.
* This circuit does not count on protection against overloads reason why it must be avoided to exceed the 2 Amperes. For this, a fuse of 2A with the emitter of Q2 can be placed in series.
