Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:

1 Watt 2.3 GHz RF Amplifier using a MRF2001: (diagram added 6/03)

10 Watt Power Amplifier: Simple Class A Amplifiers (added 4/02)

100 Watt Guitar Amplifier #2: (schematic / circuit design added 9/02)

100 Watt Guitar Amplifier Mk2: (circuit added 7/02)

100 Watt Rms Amplifier: This is a100-Watt basic power amp that was designed to be (relatively) easy to build at a reasonable cost. It has better performance (read: musical quality) than standard STK module amps that are used in practically every mass market stereo receiver manufactured today. When I originally built this thing, it was because I needed a100 WPC amp and didn't want to spend any money. So I designed around parts I had in shop. (added 4/02)

16 Watt Amplifier: (diagram added 6/03)

18 Watt Audio Amplifier: High Quality very simple unit. No need for a Preamplifier (added 9/04)

2 Watt Amplifier #1: (circuit added 9/04)

2 Watt Amplifier #3: (schematic / circuit design added 9/02)

2.3 GHz Power Amplifiers: Note: quality of text is poor. (added 4/05)

20 Watt / Channel Stereo Power Amplifier: (circuit added 2/07)

20 Watt Class a Power Amplifier: (schematic / circuit design added 9/02)

20 Watt GaAs-FET Power on 2.3 GHz: (diagram added 6/03)

20 Watt Power Amplifier: Designed to be used as car amplifier (added 4/02)

20 Watt/Channel Stereo Power Amplifier: (schematic / circuit design added 9/02)

200 Watt Amplifier: (electronic schematic / circuit added 4/02)

20w Amplifier: (electronic circuit added 4/05)

22 Watt Audio Amplifier: Simple stereo amplifier based on TDA1554... (circuit design added 10/06)

220 Watt Power Amplifier: This is a building plan for an audio amplifier with2 x220-Watt output power. Text is in Finnish. (added 4/02)

25 Watt MOSFET 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, under quiescent conditions, standby current may be 15 mA rising to 150 mA with a 50 mV input signal. A simulated frequency response is ... (added 2/07)
