The circuit is a two-stage amplifier with the output transistor operating in linear A mode with a quiescent current of approximately 180 mA. The entire amplifier consists of OOS circuit (elements C5, R5, R6). The resistances of resistors R5 and R6 determine the gain of the node. The output transistor must be mounted on a…
Leach amplifier design is very high quality and has many applications. PCB design is very good in these projects. Source eagle CAD files material list measurement values are given. The author gave detailed explanations about transistor selection, problems encountered, solutions and other issues. I am adding the translation without editing. Amplifier LVA100 I have been…
Output transistors in the 200W Amplifier circuit are TIP2955 and TIP3055. Working voltage is 2X42V DC symmetrical (2X30V AC). Power supply rectifier, filter, fuses, amplifier and low high bass control layer are on a single PCB. TL084 Op amp is used for the low high bass circuit, you can make the selection with the switch…
I implemented the “200watt 300watt 400watt 500watt Amplifier Circuit” project that I shared years ago. Actually, I wanted to do it when I shared it, but quiescent current adjustment, measurements etc. I don’t like it 🙂 But after receiving occasional feedback about this amplifier for a long time, I wanted to try it. Since the…
A more stable, stable version of the 100 Watt Mono Amplifier known as ZENER in Colombia. It can deliver 100W power with an 8 Ohm speaker and can also be used with a 4 Ohm speaker. Its noise is very low, and it does not make an explosion sound when opened. Even though I use…
Amplifier D-class Music power 500W. (RMS 300W) NE5532, IR2184, KNP9120 mosfets. A simple D-class amplifier, based on a modified version. Protection of the amplifier against a short circuit at the output, clipper Limiter. Class Amplifier Characteristics: RMS power: 300 watt Load resistance 4 ohm Supply voltage +63/-63v DC Frequency range: from 5Hz to 80-180Hz (depending…
The amplifier gained popularity with its ease of assembly, excellent repeatability and acceptable characteristics, while having a simple circuit, and of course the advantages of class-B (relatively high efficiency and good thermal stability), without the inherent distortions of this class. using the NE5532 operational amplifier, there is no need to introduce a zero offset adjustment…
Transistor 2X100W stereo and mono bass amp circuits by converting 12V battery voltage (between 11v…14.4v) SG3525 DC DC voltage amplifier circuit to around 2X30…35V. There is protection against short-circuiting in both circuits and short-circuiting of the transistors at the amplifier output and giving DC voltage. The 120W subwoofer amplifier has an adjustable bass filter circuit…
The DIY version of the Crown XLS series professional amplifier is tried and tested and is even sold as a kit. There are 300W, 600W, 800W, 1200w versions that have been applied by removing some parts without changing the design of the original circuit much, I prepared a PCB for the 400W version. Crown XLS…
100W Amplifier circuit provides high power with less material. Output transistors 2 2SC5200 NPN transistors. PNP transistor is not used for output in this amp design. The operating voltage of the 100W Amplifier circuit is 2X46V DC. If you want to operate at higher voltage (max. 2X56V DC), you should use 2SC3858 or similar power…
