Amplifier Circuits: Schematic Diagrams / CK1607 Amplifier

PCB plans and circuit diagram (schematic) for what appears to be an extremely nice 100 watt guitar amplifier. Includes preamplifier and power amplifier circuit diagram and PCBs

Shows an electronic circuit diagram (schematic) for a simple 10 Watt audio amplifier, using only 4 transistors.

1 Watt Audio Amplifier. 8 Ohms impedance. 20 Hz to 20 kHz. Small, few components.

Describes the schematic (circuit diagram) and PCB (Printed Circuit Board) for a cheap 100-150 Watt audio amplifier with few components.

Amplifier circuit for electret microphones (condenser microphones). Amplifier the audio signals picked up by the electret microphone, using 741 op-amp and a 2N2222 transistor.

This audio amplifier electronic circuit uses MOSFET transistors to create more than 25 Watts output power. Uses IRF530 and IRF9530 MOSFET transistors.

Circuit diagram for an AM radio antenna preamplifier that amplifiers the signal before it get to the AM receiver, thus making the AM radio signals stronger for better reception.

MicroStrip 2.3 GHz (GigaHertz) RF amplifier with 1 Watt RF output power.

2 channel (Stereo) Audio Amplifier with 1 watt per channel.

This simple stereo audio amplifier will amplify audio for your low-medium impedance headphones and give you left/right balance control

High quality 25 watt audio amplifier. Combining 2 would give a 50 watt stereo amplifier.

Circuit diagram and construction notes for a very nice 40 Watt FM Amplifier, with wide-band operational characteristics. Includes low pass filter design. Very good notes.

An extremely good stereo tube amplifier which produces 90Wrms per channel.

This 40 Watt FM RF Amplifier will increase the output of your FM transmitter from about 1 Watt to 40 Watts.

This 20 Watt FM RF Amplifier will increase the output of your FM transmitter from about 1 Watt to 20 Watts.

Amplify tiny audio signals fifty times with this electronic kit, and deliver them to a power amplifier cleanly and undistorted. AGC (automatic gain control) eliminates distortion. This circuit is useful in boosting the output from tape heads, microphones

The circuit is a gem; a TDA 1554 Integrated Circuit is used to produce an amplifier that will output up to 22 watts per channel with distortion typically not in excess of 0.1% thd. Sound quality is very, very high. Originally intended for use in an automo

This 150 Watt FM RF Amplifier will increase the output of your FM transmitter from about 1 Watt to 150 Watts.

Schematic for an electronic circuit that behaves as an electronic version of a Roulette wheel. Flashed 10 LEDs in sequence with slowing pace until only 1 remains illuminated.

This high gain earphones amplifier electronic circuit has a microphone, the sound from which it amplifies by a very high level so you can listen things to with lower volume easily.

Complete instructions and circuit diagram for a Geiger counter meter device, which will allow you to measure radiation levels.
