Music light effect:

This is a music light effect level circuit diagram. It looks like an old VU meter. Now we use the down-to-up music level light. Every amplifier needs this level circuit. It’s not only the beauty. It’s also for calling the sound level. This circuit runs on 12 volts. The audio input can be controlled using a 10k VR.

Transistor amplifier circuit diagram C5198:

This is a transistor amplifier circuit diagram, C5198 and A1941. This pair of transistors can make 50 watts. It’s a mono audio board. For stereo needs dual board. we can use 20-0-20 voltage to 40-0-40 voltage and 3 amperes. C5198 is positive, and A1941 is negative. We can also use another pair of positive and negative transistors. like 2sc5200 and 2sa1943.

This is the 150-watt amplifier circuit diagram using 2N3055 and MJ2955. We can use 35-0-35 voltage and 5 amperes. We can get the output to be 150 watts. It’s a mono board. For stereo, there is a dual circuit board. We can use another transistor. Here are the needed PNP and NPN transistors. Use another transistor following BCE.
