Audio oscillator
Almost any transistor will work. R1 and C1 will vary the tone.
The circuit utilizes a transistor as the primary active component, which can be substituted with various types of transistors, including bipolar junction transistors (BJTs) or field-effect transistors (FETs). The...
Audio High Gain Crystal Earphone Amplifier
This simple, one-transistor amplifier provides a voltage gain of over 1000 (60 dB) for an active aerial impedance crystal earphone. The gain is achieved by replacing the standard load resistor with a constant-current diode that supplies 1/2 mA while exhibiting...
Audio/Video Switcher
This circuit is a two-channel baseband video switcher. Buffer amplifiers U1/Q1, U4/Q4, and associated components produce a buffered 75-ohm video signal, which is routed to the switching network K1/K2/K3. Relay K1 selects either of the two video amplifiers and feeds...
1.5 W linear Power Amplifier
I will also explain how you can build a 1.5W PA transmitter. The project will include PCB, components and instructions how to make coils, assembly and testing. First let's discuss and learn about the RMS value of a sine signal....
Bomb Proof 150 Watt MOSFET Power Amplifier
In my opinion that is the best buildable high power amplifier out there. Quality of sound is just remarkable. This is a real bomb proof amplifier like the best Valve amps. Power supply circuit is also shown. Now lets see...
high power regulator
The half-linear design allows for reduced thermal considerations, as the linear regulator only needs to handle 1-5W instead of the full 75W per rail. MOSFETs operate in their linear region, just below the rated voltage for RDS(on), but they are...
Audio AGC amplifier circuit
The Audio Automatic Gain Control (AGC) circuit monitors the output signal level of an audio preamplifier. When the input signal increases, the AGC circuit automatically reduces the amplifier's gain. Conversely, when the input signal decreases, the AGC circuit increases the...
Audio Millivoltmeter
An AC millivoltmeter - calibrated in dB - with a range of 30V down to 3mV full scale (80dB range) would be extremely useful. Attach a microphone (electret mic capsules are quite good), and you have a relative sound level...
Build A Simple Twin Tee Phase Shift Audio Oscillator and Audio Amplifier
The schematic diagram presented is of a twin "T" phase shift oscillator, an audio oscillator. This oscillator derives its name from the phase shift network formed by resistors R3, R4, and capacitors C1, C2, and C3. This network shifts the...
