Electronics Help Care Amplifier circuit diagram This is a 500-watt power amplifier circuit diagram using Sanken transistors. Four Sanken transistors can produce 500 watts. The most popular transistor is Sanken 2SA1216 / 2SC2922. 2SA1216 is a PNP negative transistor, and 2SC2922 is an NPN positive transistor.
We can use 22-0-22 voltage to a maximum of 35-0-35 AC voltage. maximum 15 amperes. 15 x 35 = 525 watts can produce this circuit board. Each transistor can produce 200Watts. The collector voltage is 180V. collector emitter amperes is 17amp. and the transition frequency of 40MHz,
How to add an extra transistor:
How to add an extra transistor? A Maximum transistor amplifier can add extra transistors, but it will not work if we don’t increase the amperes or voltage. If we want to add an extra transistor, then we have to increase the voltage and amperage. like the voltage is 35-0-35 and 3 amperes for 2 transistors. If we add an extra 4 transistors, then we have to add an extra 4 amperes. And the voltage can be 45-0-45 maximum.
This is the Preamplifier circuit with a graphic equalizer for the amplifier. This diagram runs on 12 volts. It’s a stereo diagram. Treble, midrange, and bass can be controlled using this board. Every amplifier needs this type of circuit to control the sound quality.
We can get many amplifier circuit diagrams. This circuit can be used in a 2.1 sound box. We can make a subwoofer amplifier using this diagram. To make a subwoofer, we need a low-pass filter circuit. To get the lowpass filter circuit, please visit here LOWPASS FILTER. We need this low-pass filter to make a bass amplifier for 2.1 audio. This low-pass filter makes the sound only bass. It’s also a pre-amplifier. We can use this circuit in any amplifier to make a subwoofer amplifier.
