The small amplifier consists of 3 transistors and passive components. It can deliver 400mW power at 9VDC operating voltage, speaker impedance is 8-OHM. The input signal is between 200mV and 2V. The quiescent current is adjusted with the R10 50K trimpot. When the amplifier is idle (without a speaker connected and input signal) the current…

Hi-fi Amplifier Technical data; Continuous output power with 4-OHM Speaker Supply voltage 15V: 3.2W Supply voltage 12V: 2.05W Supply voltage 9V: 0.97W Frequency response: (-3dB) 30-100kHz THD: 0.09 Signal-to-noise ratio: 80dB…
250W amplifier has been tested in the field for a long time, high quality and high power. You can use it with 2 8 ohm speakers or one 4 ohm speaker in parallel. It has low harmonic distortion and high sound quality. Gain Adjustment and Technical Details Gain: This is the sensitivity to the input…
8-OHM RMS 100W Amplifier ZENER’s 500W version. Semi-complementary ZENER amplifier, the sound is very clean and there is no pop sound at the opening. As long as you make it with original and quality components, you can use it for heavy sounding jobs. One of the biggest advantages of this amplifier with differential torque regulation…
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…

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…
