2.1 Amplifier Transistor-based 2SC5200-2SA1943
This is my DIY project try make 2.1 amplifier that have 3 channel output there is Subwoofer Out, Front left out and Front right out.
The output stage uses transistor pair of 2SC5200 and 2SA1943 in a class AB amplifier, it can give power about 85W before clipp @4 ohm load / channel or about 256W total power.
This amplifier has some feature like : midbass control, treble controll, and volume controll for the stereo front channel, and a separated volume controll for the subwoofer channel.
The preamp power supply powered from the main amplifier that regulated with 12 volt ic-based regulator like L7812 and L7912 to make constant voltage.
This amplifier need 24-0-24/10A symmetrical transformer
what does it sounds like? please check the video on barlex respectaizer youtube channel
