Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
1.5kW Power Amplifier -  Just the thing for those for whom no amount of power is enough  (schematic added 6/07)
100 Watt Amp Circuit (Rod Elliott) -  Guitar amplifiers are always an interesting challenge. 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. There is no amp that satisfies everyone's requirements, and this offering is not expected to be an exception.... (design added 01/2010)
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 ….(added 4/02)
11 Watt Audio Amplifier -  A 10-W Design giving subjectively better results than class B transistor amplifiers .  (electronic design added 08/08/08)

11 Watt Power Amplifier -  Simple Class A Amplifiers (added 4/02)
12 Volt powered, 4x15 Watt audio amplifier  -  Using car audio chips and intended for installation inside a computer. [Manfred Mornhinweg]
15dB UHF TV Antenna Booster -  This is an UHF band TV antenna preamplifier circuit With 15dB gain to build easily. It is formed based on BF180 UHF Transistor. The first stage is an band pass filter constructed by the C1, CV1, L1, L4, C7 and C3, the second stage is a base-common…(electronic design added 08/08/08)
16 Watt Amplifier -  this circuit provides 16 watts of amplification. it is built using two LM383 power audio amplifiers. use suitable heat sinks with the ic's. ….(diagram added 6/03)
18 Watt Audio Amplifier -  Can be directly connected to CD players, tuners and tape recorders. Do not exceed 23 + 23V supply. Q3 and Q4 must be mounted on heatsink. D1 must be in thermal contact with Q1. Quiescent current (best measured with an Avo-meter in series with Q3 Emitter) is not....(electronic circuit added 6/07)
