#2n3055 transistor amplifier circuit how to#
This is how to connect the amplifier module to the speaker, power supply and audio input. Diode bridge (rectifier) ​​of 15 Amps: 1.
If the stereo channel, the amperage should be doubled.
Transformer for the mono amplifier should be 35 + 35 volts AC with a minimum of 3 amps. Power Supply Circuit for 120W Power Amplifier Use mica between the transistor and the heatsink. The points are: prevent circuit shortage, use proper isolator and use thermal compound for maximum heat spreading to the heatsink. How to mount the transistors to the aluminium heatsink, see below image: potentiometer of 20K if you want to add volume control. Zener diodes between 20 and 24 volts : 1. All of the components is easy to gathered from the electronic store. #2n3055 transistor amplifier circuit generator#
The frequency generator / multivibrator is built based on transistors too. 33 Ω (1/4W) – orange, orange, black : 1 This is the scheme diagram of 500W power inverter circuit which build using 10 pieces of well-known NPN power transistor 2N3055 to amplify the AC signal produced by multivibrator.10 Ω to (1W) – brown, black, black : 1.100nF (104) 100V nonpolar polyester capacitor : 2.470pF (471) nonpolar ceramic capacitor : 2.100pF (101) nonpolar ceramic capacitor : 2.
470nF (474) nonpolar polyester capacitor: 1. The well-known power transistor pair of 2N3055 and MJ2955 used in this circuit. +/- 50V symmetrical (split/dual polarity) power supply with minimum 3A electric current should be used for maximum performance. This is 120W power amplifier schematic using TO-3 package complementary transistors, NPN and PNP polarity.
