Stereo Pre-amp with Volume and Tone Control
This is the circuit diagram of stereo pre-amp with volume and tone control. When using one of our amplifiers (big or small), you always need a volume control and preferably…
Class D Amplifier for ATtiny15L
…the bridge output amplifier is designed gate-4 and not (561LA7). The amplifier incorporates composite transistors KT972A, KT973A. Adjustment of the amplifier should start with the pre-amplifier assembly, first of all,…
Asymmetric Pre-amplifier Circuit
This Asymmetric Pre amp circuit is designed to amplify a signal little AF stereo line-level, and has an unbalanced input and output. It is perfect to add that little something…
100W PEP 420-450Mhz PUSH-PULL LINIER AMPLIFIER
This is 100 watt linear amplifier and may be built using two MRF309 transistors in push-pull, requiring only 16 watts drive from 420 to 450 MHz. The 100 watt linear…
Hydrophone Preamplifier based on Op-Amp OPA37
…it’s really very simple and uses only conventional components. The transducer used, is piezo type and has a relatively high output impedance, which requires a preamp with a high input…
12W amplifier circuit based 741 Op Amp
This Amplifier is 12 watts and to operate this is use source of dual symmetric ± 12 volt. The 741 provides the required gain while the speaker unit driven by…
Balanced Input/Output Pre-amplifier Circuit
This Balanced pre amp circuit is designed to amplify a little line-level audio signal (from dB to 20 dB), and has balanced inputs and outputs. The scheme uses only conventional…
