1.5 W Power Amplifier type class-C -  This project will explain the basic function of a class-C transmitter. I will explain how to dimension a transmitter and the purpose of the different components. I will also explain how you can build a 1.5W PA transmitter. The project will include PCB, components....(added 07/07/07)
1.5kW Power Amplifier -  Just the thing for those for whom no amount of power is enough  (schematic added 6/07)
10 Watt Power Amplifier -  Simple Class A Amplifiers (added 4/02)
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)
100W Audio Amplifier -  This is an exceptionally well designed amplifier, with a lot of power reserve, high fidelity, low distortion, good S/N ratio, high sensitivity, low consumption and full protection….(electronic design added 08/08/08)
100W RMS Amplifier -  This is a 100 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 a 100 WPC amp and....(added 6/06)
12 Watt Valve Guitar Amp -  (electronic diagram added 2/07)
2.8-GHz prescaler keeps cost down -  20-Jul-00  Published in EDN  The prescaler in Figure 1 inexpensively extends the range of a frequency counter by dividing the input signal’s frequency by a factor of 1000. The guaranteed input-frequency range…. [Design Idea by Neil Eaton, Emsys Engineering, Peterborough, ON, Canada]
