2000: Watts Amp
0 Comments - in DC Power Supplies
A very simple variable power supply with a DC output voltage adjustable from 1-3- Volts, with a maximum DC current of 5 Amps. Uses LM338 DC voltage regulator IC.
3 Amp Variable DC Power Supply
Provides 3 amps current at 3-30 Volts DC. Reduces ripple voltage to almost non-existant.
6-10 Watt Stereo Amplifier Kit
A stereo smplifier kit which outputs up to 4 watts per channel, giving a total of 10 watts.
Stereo Amplifier 44 Watt electronic kit
The circuit is a gem; a TDA 1554 Integrated Circuit is used to produce an amplifier that will output up to 22 watts per channel with distortion typically not in excess of 0.1% thd. Sound quality is very, very high. Originally intended for use in an automo
An extremely simple and cheap DC power supply with variable voltage (1.2-25 Volts) control. The circuit uses an LM317 integrated voltage regulator Ic.
CTE TX500 Plus - Professional 500 Watt FM Transmitter
This professional FM Transmitter offers a whopping 500 Watts output power in the 88 - 108 MHz band. The transmitter itself is digitally controlled and is extremely user friendly.
Circuit diagram and construction notes for a very nice 40 Watt FM Amplifier, with wide-band operational characteristics. Includes low pass filter design. Very good notes.
LM317 Variable Power Supply
A very basic power supply that can be adjusted over a range of about 1.5 to 35 volts DC. If you add a heat sink (included), you can run it as hot as 2 Amps output; otherwise about 60 mA @ 12 volts. This is a text book circuit using an LM317, which is a 3
