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

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)

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) |

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….
