Jika anda merasa 50 watt masih kurang memadai anda bisa mencoba rangkaian power amplifer 100 watt dan skema power amplifier 150 watt. Lihat juga rangkaian loudspeaker driver dan inverting amplifier. Buat anda kususnya adik adik pelajar yang masih belajar sebagai npemula dalam melakukan perakitan elektronika di bawah ini saya berikan beberapa contoh rangkaian amplifier yang kami salin dari skema TULUS KIT yang pernah jaya bbeberapa tahun lalu. Seiring dengan berkembangnya teknologi memang akhir akhir ini rangkaian elektronika semacam ini sudah mulai di tinggalkan dan tergeser oleh.

Transistor PA by sanken. Sanken 2SC2922 - 2SA1216 - Output 200 Watt - Maximum voltage of 180V - Maximum current of 17 amperes 2. Sanken 2SC3858 - 2SA1494 - Output 200 Watt - Maximum voltage of 200V - Maximum current of 17 amperes 3. Sanken 2SC3264 - 2SA1295 - Output 200 Watt - Maximum voltage of 230V - Maximum current of 17 A Of the three types of sanken, the whole power equals 200Watt. So don't speculate which is the most wattage among the three.

The difference only the max V. Even though the three series transistors the price is different, especially Sanken 2SC3264 - 2SA1295 which is more expensive than the others.

I've made gainclone amplifier that uses a LM3886 chip. It's one of the best compact HiFi amplifiers. It is a Class AB-A (conjugate) amplifier that has a fully symmetrical structure (push-pull), this mean that the sine waves produced, will produce a +, - output. A 25 volt (+/- Dual Rail), 5 Ampere, toroidal transformer was used to supply electricity for the amp. There's also a PCB Layout provided for the project. I found an old CPU processor attached to a gorgeous heatsink & fan, I recycled both of them and drilled holes for it to be mounted on the LM3886 chips. Specifications: - Maximum Output Power: 68W RMS - 108W Peak - Frequency Response: 7Hz-25kHz (Filtered ⇒Linkwitz) - THD:%0.03 at 60W - SNR: 110dB at 60 W - 92.5dB at 1W - Output Class: AB-A (Conjugate) - Auxiliary Features: DC/AC Short circuit protection and thermal protection.

- Working Voltage/Power: 12-94 Volts (Dual Rail), 1-10 Amperes - Audio Features: Input Mute Funtion (100% silent = no input) Too bad I had a late documentation, that's why I only have a few pictures of the steps and procedures. Due to the late documentation, I had to get images from the source. Some of the pictures are not mine, there are no claims that the PCB designs are mine nor the diagrams, although there where some modifications made by me for the amp. What Is A Gainclone? Back in 1999, relatively unknown manufacturer released the 'Gaincard' to rave reviews. It immediately caused controversy because it was based around a $5 power amplifier IC (Integrated Circuit), yet a typical setup would cost you around $3300.

A Gainclone in the other hand refers to any DIY amplifier that uses a LM3875/ LM3886 as it's main component. What's So Special About It? The gainclone only uses small amounts of space, it's built with a minimal supply of components, yet giving a great HiFi result. It beats the hell out of those modern HiFi amps, it produces 2x68 watts of power, with a Total Harmonic Distortion of 0.03%THD and built on a 2x3 PCB board! So why doesn't the audio industry use it?

I'm not really sure. All of these sounds 'too good to be true', I recommend this project for those who are still starting on their DIY HiFi amp hobby, since it only uses some few components. What's A Power Amp? A power amp is a amplifier with no preamp, volume control, tone control, or any auxiliary devices attached to it. It's just pure simplicity. Coming Soon: DIY HiFi Preamp With Tone Control (Works With The Gainclone).

I can tell that parts in the US are highly expensive. Here in the Philippines a typical resistor would cost 0.25 centavos ($0.0006), while in america, a typical resistor would cost $1 each. There's a large difference. Also, parts are available here almost everywhere. That's the beauty of living here when you have a hobby of electronics. My project cost me P870.00 ($21.75) all in all.

Parts: _______________________________________________ Others: - LM3886 amplifier chip (2pcs.) - 25 Volt, Dual Rail Transformer (Toroidal/ IE) - 2x3 PCB board (2pcs.) - Large Heatsink (2pcs.) - Cooling Fan (1pc.) - Plastic/ Metal Enclosure(1pc.) - AC Cable _______________________________________________ Resistors: _______________________________________________ Capacitors: _______________________________________________. The LM3886 is the brother of the LM3875. It's the improved version. It produces a higher output wattage, and thermal and mute features are added too. There are two types of LM3886 IC. One of them is unisolated LM3886T and the other one is isolated LM3886TF. Be careful not to mess with the isolation.
