However, the circuit is very stable at my place and provides a clean-output through seven (7) element Butter-worth low-pass filter. Circuit Diagram: Notes: The heart of the circuit is 2SC1946A VHF RF power transistor. The transistor is specifically designed for operation in frequencies up to 175 MHz, with very good results. As you can see, the power line is well decoupled. The amplifier current can be over 5 amps. All the coils are made from 16gauge laminated wire (or Silver copper wire can do best) and the RFC can be of HF toroid core (as shown in the picture) or 6 holes ferrite bead.C3 and R1 forms snubber circuit while R2 and C6 prevent the amplifier from self-oscillation at VHF, sometimes you need to add 180 ohms in parallel with L7.That will cause the amplifier to dissipate UNDESIRABLE VHF thereby r...

This is a 200 Watt Amplifier Circuit Diagram that uses a TDA2030 IC which is an audio power amplifier 200 watt low cost. The 200 watts can be achieved with a load impedance of 4 ohms. The TDA2030 can typically provide up to 14 watts into a 4 ohm load, but if used in bridge mode and we use some cheap power transistors we can get to 200 watt. The design of this amplifier circuit 200 watt audio is very simple and requires few external components. For best performance, you can use a source of 28 volts (+ / - 14 volts), not more than 44 volts (+ / - 20 volts).  As you can see in the diagram, for this power amplifier circuit you need high capacity capacitors and a power supply high current. All transistors and ICS should be mounted on a heat sink to prevent damage by temperature. For small value resistors (1 ohm, 2.2 ohm) resistors use 2-5 watts.  200 Watt Amplifier Circuit Diagram using TDA2030

Using a mobile phone while driving is dangerous. It is also against the law. However, you can use your mobile phone as a powerful music player with the help of a stereo power amplifier. This does away with the need of a sophisticated in-dash car music system. Most mobile phones have a music player that offers a number of features including preset/manual sound equalisers. They have standard 3.5mm stereo sockets that allow music to be played through standard stereo headphones/sound amplifiers. Nokia 2700 classic is an example. A car audio amplifier with 3.5mm socket can be designed and simply connected to the mobile phone output via a shielded cable with suitable connectors/jacks (readymade 3.5mm male-to-male connector cable is a good alternative). Fig. 1 shows the circuit of car stereo player. It is built around popular single-chip audio power amplifier TDA1554Q (IC1). The TDA1554Q is an integrated class-B power amplifier in a 17-lead single-in-line (SIL) plastic power package. Fig. 1: ...
