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
This audio amplifier electronic circuit uses MOSFET transistors to create more than 25 Watts output power. Uses IRF530 and IRF9530 MOSFET transistors.
MicroStrip 2.3 GHz (GigaHertz) RF amplifier with 1 Watt RF output power.
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.
Shows an electronic circuit diagram (schematic) for a simple 10 Watt audio amplifier, using only 4 transistors.
Describes the schematic (circuit diagram) and PCB (Printed Circuit Board) for a cheap 100-150 Watt audio amplifier with few components.
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.
Schematic / circuit diagram for a tunable transistor electronic organ. Easy to tune the notes that are generated.
This simple stereo audio amplifier will amplify audio for your low-medium impedance headphones and give you left/right balance control
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.
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.
Stereo Pre Amplifier Kit
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
Stereo Amplifier 44 Watt electronic kit
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
