10 W Bass-boost Audio Amplifier Schematic Description: This architecture is based on the 18 Watt Audio Amplifier, and was developed mainly to amuse the requests of correspondents clumsy to locate the TLE2141C chip. It uses the boundless NE5532 Dual IC but, obviously, its ability achievement will be comprised in the 9.5 – 11.5W range, as [...]
The amplifier circuit output is 3 watts in tube Class A with the 6BX7 tubes used to draw. The project has a normal gain entry to the regular “Fender-like set of” full-range control, treble, bass, midrange and volume. It is also possible for extra high gain jack, the second phase of the tunnel and its own gain control. [...]
Here is a 60 to 100 Watt Amplifiers circuit, the electronic designer was developed for the (relatively) easy to build at a reasonable price. It has a better performance (ie: musical quality) than the default STK module amps, in practically every mass market stereo receiver manufactured today. As I am behind this thing, it was [...]
Portable and small unit, Can be built on a veroboard Firstly, I’d like to stress that the intended use of this circuit is only one of many possible applications. Apart from the obvious usage as a headphone amplifier, the circuit can be used for a range of applications where a wide bandwidth low power amplifier [...]
3V Battery powered, High Performance unit This amplifier can be directly connected to CD players, tuners and tape recorders. It is tested with several headphone models of different impedance: 32, 100, 245, 300, 600 & 2000 Ohm.Schematic shows left channel only. B1, SW1, J1 & C3 are common to both channels. R3 value was calculated [...]
