It requires supply voltage 12V. Easy to build and cheap. If you want a mini amplifier circuit. We have a lot of ways to do it. Today we use only IC.
It is comfortable than the transistor. Of course, we no have one way. Today let me tell you. To use TBAM.
The producer designed for audio frequency class b amplifier. First, we enter the power supply voltage to the circuit. Then, connect the input signal. Even have many parts but easy to understand. Circuit diagram. In Mono style is a few parts and very cheap.
You can put them on the universal PCB. It saves time. If your ring bell of the telephone is too light. Come here this way. This circuit may be can help. It is a telephone amplifier circuit. And VR1 controls the volume of the sound high or low level. This circuit requires enough power supply. Do you have this one? If you do not have it. I always try to make Electronics Learning Easy.
