600W Audio Amplifier - ….(electronic schematic added 08/08) |
|
60W Bass Amplifier - This design adopts a well established circuit topology
for the power amplifier, using a single-rail supply of about 60V and
capacitor-coupling for the speaker(s). The advantages for a guitar amplifier are
the very simple circuitry, even for comparatively high power outputs, and a
certain built-in degree of loudspeaker protection, due to capacitor C8,
preventing the voltage supply to be conveyed into loudspeakers in case of output
transistors' failure. The preamp is powered by the same 60V rails as the power
amplifier, allowing to implement a two-transistors gain-block capable of
delivering about 20V RMS output. This provides a very high input overload
capability. ….(design added 11/08) |

60W MOSFET Amplifier - To celebrate the hundredth design posted to this
website, and to fulfil the requests of many correspondents wanting an amplifier
more powerful than the 25W MosFet, a 60, 90W High Quality power amplifier design
is presented here. Circuit topology…(design added 04/05/06) |

60W Power Amplifier - This paper gives a practical example of the design of an
off-line switching power supply. Factors governing the choice of a discontinuous
flyback topology are discussed. The design uses a pulsed-width modulation (PWM)
control scheme implemented with a Unitrode UC3840 IC...(circuit added 04/05/06) |
|
60W Power Amplifier (Jacint Chapo) - This is a simple and low cost 60W power
amplifier. The optimal supply voltage is around 50V, but this amp can work from 30
to 60V. The maximum input voltage is around 0.8, 1V. As you can see, in this design
the components have a big tolerance, so you can build it with almost any components
that you can find at home. The output power transistors can be any NPN types, but do
not use Darlington types. ….(design added 11/08) |
|
70W Class AB Hi-Fi Amplifier - This project considers the development of a 70W
Hi-Fi Power Amplifier for use as part of a Hi-Fi separates music system. The design
is a fairly simple circuit topology, which is easy to understand and the author
believes that the finished result sounds very nice indeed. The web posting is
developed from an original design document available in pdf below. The detailed
design issues are discussed in the pdf, while this posting discusses the more
practical issues involved in producing the amp. ….(circuit design added 11/08) |

78 RPM & RIAA Phono Equaliser - Multi Standard 78 RPM and RIAA Phono Equaliser
handles all "standards" (added 6/07) |

8 Channel Passive Summing Busses - balanced and unbalanced input designs
(circuit design added 08/08/08) |

8 Channel Summing Buss with Level, Pan, & Master controls - (electronic circuit
added 08/08/08) |

8 Watt Amplifier - (circuit / schematic added 6/03) |
|
8 watt audio amp (Aaron Cake) - Here is the schematic for an 8 watt audio amp.
This amp can be used as a simple booster, the heart of a more complicated amplifier
or used as a guitar amp. (diagram added 08/08/08) |

8 x 8 Audio Video Switch - (electronic Circuit added 03/06) |
|
80 Watt Amplifier #2 - Uses LM12 chip (app note added 4/02) |
|
80W Tube Monoblock Amplifier - My goal was to design a high-powered
wide-bandwidth amplifier with the finest sound and to keep it simple but not too
simple. I rejected single-ended (SE) designs because of their low power….(electronic
design added 04/05/06) |
