(electronic design added 06/07) |
|
2 Tone Audio Oscillator use for SSB Tests - (electronic schematic / circuit added 2/07) |
|
2 Tone Train Horn - (schematic / circuit added 10/02) |
|
2 Watt Amplifier (Andy Collinson) - Low distortion Amplifier using discrete components (added
5/02) |
|
2 Watt Amplifier (red circuits) - This amplifier was designed to be self-contained in a small loudspeaker box. It
can be feed by Walkman, Mini-Disc, iPod and CD players, computers and similar devices fitted with line or headphone output. Of course, in most cases you will have to make two boxes to obtain stereo....(circuit added 9/04) |

20 W/Ch Stereo IC Amplifier - Based on the versatile LM1875 from National Semiconductor (added 6/07) |
|
20 Watt Audio Amplifier (Aaron Cake) - Simple stereo amplifier based on TDA1554... (circuit design added
06/06) |
|
20 Watt Power Amplifier - The LM1875 is a monolithic power amplifier offering very low distortion and high
quality performance for consumer audio applications...(added 04/2002) |
|
20 Watt Stereo Amplifier (Randy Linscott) - This circuit is very basic to build and puts out great
power for your car or home. Keep all leads as short as possible….(added 08/08/08) |
|
200 Watt Amplifier - (electronic schematic / circuit added 4/02) |
|
200W MOSFET Amplifier - A compact audio powerhouse ideal for guitar or PA work or for use as
a general-purpose subwoofer or hifi amplifier. Many people prefer Mosfets because of their legendary ruggedness. Altronics had a Mosfet amplifier module which produced 200W…(circuit added 04/08) |
|
20W Bridge Audio Amplifier - 20W Bridge Audio Amplifier kit, based on the TDA2005 IC, a class B
dual audio amplifier, specifically designed for car radio applications etc..(design added 08/08) |
|
20W T-AMP - This amplifier is a standard datasheet application of Tripath TA-2020-020 T-class
IC. It offers 20W on 4ohm load with efficienty of up to 88%. The whole amplifier was bought as a AMP6 kit from 41hz.com. The PCB board looks really good and the copper on both sides is quite thick. The kit contains only high quality components such as 1% metal film
resistors or Panasonic FC input capacitors. Because of such high efficienty the chip doesn't really require a heatsink. I used such a big one only because I had it. Before starting soldering please read the Assemble Manual so that even beginers will cope with building
this amplifier. For more information you can visit the AMP 6 forum. ….(electronic schematic added 11/08) |

21W Class AB amplifier - This is an instrument amplifier for monitoring music when on stage.
It provides 21W output power of this little design. Previously I had a decent 10W amplifier (RED Free Circuits), but we blew that one somehow. Now I will put this into the old box. I haven't built it yet, but the simulations say it works as I designed. In this design,
wiring is important due to no differential amplifier. I might need to add ripple rejection with a zener as in the above design. ….(circuit design added 11/08) |
