The -12 volt supply, like the +12 volt supply, uses discrete components rather than a 7912 voltage regulator IC. Here, we use a 1N4742A Zener diode, rated at 12 volts, 1 watt, as the main regulating element. The power supply shown in the above schematic diagram uses a Zener diode as the main regulating device, [...]
This is circuit Fix power supply Regulator 40V 2A for main Power Amplifier 30W. It is use IC LM317T (Hot IC Variable Regulator) and Transistor TIP42 for boost up Current to 2A max . Other detail see in circuit. A very good and powerful Regulated Power Supply section was implemented by simply adding a PNP [...]
This design is based on the 18 Watt Audio Amplifier, and was developed mainly to satisfy the requests of correspondents unable to locate the TLE2141C chip. It uses the widespread NE5532 Dual IC but, obviously, its power output will be comprised in the 9.5 – 11.5W range, as the supply rails cannot exceed ±18V. As [...]
