| 12V DC power supply and 5V using a 2N3055-LM309 |
This circuit is a voltage down model DC-DC converter step. This will allow you to input voltage of 9V DC 12V DC 6V and 7.5V depending on the size of the 1A current change - I think of the two amplifiers. This is for voltage circuit of the position of the one with a Zener diode is easy to cultivate. You have a 2N3055 transistor as it is strong. Advanced tallly trend go would be helpful to read the full to be thoroughly engaged please add
