200W ATX PC Power Supply - This power supply has ATX design and 200W
performance. I was drawed diagram, when I repaired this power supply. This power
supply circuit uses chip TL494. Similar circuit is used in the most power supplies
with output power about 200W....(electronic design added 6/07) |

200W audio Amplifier - ….(Circuit design added 08/08) [Site is
underconstruction right now] |
|
20dB VHF Amplifier - The amplifier is a circuit of high frequency RF with
distinguishable materials. The amplifier as circuit strengthens the tendency of
signal with concrete aid, depending on the frequency of signal. If the frequency
of signal is included in the limits of spectrum of frequencies….(electronic
schematic added 08/08) [Site is underconstruction right now] |

20W Amplifier (Aaron Cake) - The 22 watt amp is easy to build, and very
inexpensive. The circuit can be used as a booster in a car audio system, an amp
for satellite speakers in a surround sound or home theater system, or as an amp
for computer speakers....(electronic circuit added 4/05) |

22 Watt Stereo Amplifier - The 22 watt amp is easy to build, and very
inexpensive. The circuit can be used as a booster in a car audio system, an amp
for satellite speakers in a surround sound or home theater system, or as an amp
for computer speakers. The circuit is quite compact and uses only about 60
watts.….(electronic schematic added 03/08) [Randy Linscott, designer] |

25 Watt MosFet Audio Amplifier - High Quality simple unit. No need for a
Preamplifier (added 9/04) |
|
2W Amplifier - Amplifier operates in Class AB mode; single 470R preset
resistor controls quiescent current flowing through BD139/140 complimentary
output transistors. Adjustment here, is a trade-off between low distortion and low
quiescent current. Typically,.... (added 2/07) |
|
3 Transistor Audio Amp 50 Milliwatt - Here is a little audio amplifier
similar to what you might find in a small transistor radio. (added 4/02)
|
|
30 Watt Power Amplifier - Ultra-Low distortion30-Wattpower amp (added 4/02)
|
|
300W Subwoofer Power Amplifier - Please note that specification for this amp
has been upgradded , and it is now recommended for continuous high power into 4
Ohms, but You will need to go to extremes with heatsink (fan cooling is highly
recommended). It was originally intended for "light".... (added 2/07) |
