Guitar Control
Stand-alone, 9V battery powered unit, three-level input selector, three-band tone control. This preamplifier was designed as a stand-alone portable unit.
The described preamplifier is a compact, battery-operated device that operates on a 9V power supply, making it suitable for portable applications....
General purpose preamplifier
Limited information is available regarding the operation of the LM382, as the majority of its circuitry is integrated within the IC. Most components responsible for frequency determination are located on the chip, with only capacitors being externally mounted. The LM382...
Vanda F-9500A preamplifier b
Figure 3-2 (b) represents the second half of the circuit, where transistors VT17 to VT31 are configured as power amplifiers and pre-amplifiers. This section is structurally identical to the operational integrated circuit IC2 and includes zero servos. The circuit is...
High-End Audio Modular Preamplifier
This circuit is not easy to build, but it provides excellent audio quality. It serves as a high-quality preamplifier, capable of driving high-quality power amplifiers while delivering good sound.
The described circuit functions as a high-fidelity audio preamplifier, designed to enhance...
Preamplifier and high-to-low impedance converter
This circuit matches the very high impedance of ceramic cartridges, providing unity gain and low impedance output. By "loading" the cartridge with a 2.2MΩ input resistance, the cartridge characteristics are adjusted to closely compensate for the RIAA recording curve. The...
Stereo Electret Mic Preamplifier
This is a simple stereo electret microphone preamplifier circuit. For optimal performance, it is recommended to use solid or film capacitors and metal film resistors. The circuit is based on a single IC, the LM358. It is straightforward, cost-effective, and...
Magnetic pickup pre-amplifier circuit
A preamplifier for magnetic pickups of record players is presented. The uA 741 is utilized as an AC-coupled non-inverting amplifier operating on a single supply. The amplifier gain is determined by the feedback components, where C2 manages the low-frequency roll-off...
Stereo Preamplifier with adjustment tone circuit
A simple preamplifier circuit is often required, utilizing a few components for ease of construction. This circuit employs an operational amplifier, specifically the Motorola TCA5550, which features a dual amplifier configuration. It provides outputs for adjusting volume, balance, treble, and...
preamplifier for ecm microphone
Both transistors should be low-noise types. The original circuit uses the BC650C, which is an ultra-low noise device. These transistors are now hard to find, but the BC549C or BC109C are good replacements. The circuit is self-stabilizing and will set...
