Altec 1566 vacuum tube mic preamp and direct box
V1 and V2 are 12AX7 dual triodes. Each half of V1 is wired as a Class A voltage amplifier in a configuration known as Common Cathode. By comparison, both halves...
Low Noise Design Schematics
I liked the idea of distributed active RIAA correction and also the concept of using negative feedback to linearize the input stage. Now, the original Collin de...
Frequencies and Filters
One of the limitations which affect all real amplifiers is that they all have a finite Signal Bandwidth. This means that whatever amplifier we build or use, we ...
LM386 Audio Amplifier
I picked up an LM386 Low Voltage Audio Amplifier. A little poking around and I found National Semiconductor`s data sheet, showing a schematicthat requires only ...
push-pull 300B power amplifier
Most of the devices used in amplifier output stages are intrinsically seriously non-linear; the worst of all are transistors (both bipolar and FET) which are al...

Transducer amplifier circuit
The power requirements for driving light aircraft flightsim transducers is not so high; about 20W (real Watts, RMS power). Attention has to be paid to the ampli...
Voltage Controlled Gain Video Amplifier
Gain adjustment will be more flexible if it controlled by a voltage signal, since we can use many methods to provide user interface. We can control it by a.....
Magnetic Phono Cartridges Transistor RIAA Preamp
The following two-transistor circuit is a pre-amplifier circuit for magnetic phono cartridge, which is characterized by its frequency response defined by RIAA s...
General-Purpose AF Power Amplifier
This is a schematic diagram of general-purpose audio frequency (AF) amplifier circuit. This circuit uses cheap 1/4-W resistors, no high precision needed so.....
Basic FET Amplifier
This is The Fet Amplifier circuit. This circuit uses FET transistor. The gate of the FET must be negative with respect to the source, so a bias can be achieved ...
Transistor Common Base Amplifier
As far as AC is concerned, the base is connected to the ground by the C3. Therefore, both input and output are connected to the base (common base amplifier).....
Transistor Class A Power Amplifier
The transistor is biased in class A. That`s mean the collector current flows all the time. This current can increase or decrease, caused by the input signal.....
DC Coupled Transistor Amplifier
This is a The Directly (DC) Coupled Amplifier circuit. This circuit is built from NPN transistor and PNP transistor. This circuit is used to amplify a DC.....
