X10 operational amplifier

This circuit greatly expands upon the capabilities of circuit 02. A thermocouple signal is quite small, and the long thermocouple leads often induce quite a bit of noise into the system. This new circuit is far more accurate, stable,...

The NP-100v12 is a straightforward headphone amplifier designed for entry-level builders to assemble and listen to their own creation. The term "builder" refers to individuals with electronic experience and innovation, allowing them to create a device rather than merely...

This module utilizes an unconventional topology while retaining the fundamental operational amplifier circuitry of the main module, with some modifications in resistor values. A distinctive feature of this circuit is the incorporation of six-way switches instead of the more...

Buffers are a specific category of amplifiers, and power buffers are a subset of power amplifiers. The defining characteristics of all buffers include unity gain and a low impedance output, ideally accompanied by low distortion. When examining commercially available...

The 60 Watt linear amplifier is a simple all solid-state circuit using power MOSFET IRF840. The IRF series of power transistors are available in various voltage and power ratings. A single IRF840 can handle a maximum power output of...

The circuit depicted involves a main amplifier balanced by an electromagnetic pickup, line amplifiers, and a high tone control circuit. It includes components for an electromagnetic player, radio tuner, tape playback, and line input. The preamplifier utilizes an NE5532...
