he active component required is just the main power amplifier chip STK465.Ģ0 Watt Amplifier using LA4440 - This is the circuit diagram of a simple 19 watt amplifier using IC LA4440 from Sanyo. Just look at the PCB layout of this circuit. This amplifier circuit will deliver 25W on each output channel.Ģ×30W Audio Amplifier with STK465 - Simple circuit with higher power output, this amplifier circuit is very easy to build. Great output power with only using single chip.Ģ×25W Stereo Power Amplifier with STK4141II - Here the stereo power amplifier based on single IC STK4141II. _ Designed by RL Campbell KK7BĢ×100W Power Amplifier with STK4231II - Here the high power audio amplifier dual output at 100W max each output channel. _ Designed by Carlos FeldmanĢ.3 GHz Power Amplifiers - Note: quality of text is poor. Carlos has used this amplifier on his AM radio for many years. _ Designed by Andy Wilsonġ8W Audio Amplifier - High Quality very simple unit - No need for a preamplifier _ Contact: IQ TechnologiesĢ Watt Amplifier - An audio amplifier made from discrete components with 2 Watts audio power into an 8 ohm load. it is built using two LM383 power audio amplifiers. The first stage is an band pass filter constructed by the C1, CV1, L1, L4, C7 and C3, the second stage is a base-commonġ6 Watt Amplifier - This circuit provides 16 watts of amplification. It is formed based on BF180 UHF Transistor. _ Designed by Manfred Mornhinwegġ5dB UHF TV Antenna Booster - This is an UHF band TV antenna preamplifier circuit With 15dB gain to build easily. The IC can be also operated from 12V and that makes it applicable in car audio systemsġ2 Volt powered, 4x15 Watt Audio Amplifier - Using car audio chips and intended for installation inside a computer. The IC can easily deliver 10W to a 4 Ohms load at 18V DC supply voltage. There is no amp that satisfies everyone's requirements, and this offering is not expected to be an exception _ Designed by Rod Elliott ESPġ0W Amplifier using TDA2003 - Here is the circuit diagram of a 10W audio amplifier using the popular TDA2003 IC from SGS Thomson. The tone controls, gain and overload characteristics are very individual, and the ideal combination varies from one guitarist to the next, and from one guitar to the next. _ Designed by Guy Roels ON6MUġ00W Guitar Amplifier - Guitar amplifiers are always an interesting challenge. The design is a goodīalance between output power, physical size. Transmitters on the amateur bands 15 and 17 meters can be The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM Linsley Hood, M.I.E.E.ġ0 watt HF 17 meterband Amplifier - This project and your efforts will provide you with a 0.55.3 watt input to easily 10 watt output. 10 Watt Audio Amplifier - This page describes an antenna, a 1 watt final output stage, and a transformation network for radio experiments at 187 kHz _ Designed by J.
