4W Amplifier - I have recently included a page about AF amplifers for use with
Homebrew rigs. In this I mentioned that I may include a practical one-watt circuit,
complete with PCB foil and layout. Here it is, but I have taken the liberty of
engineering it to provide 4-watts of AF output and with a frequency response almost
suitable for Hi-Fi applications.....(design added 2/07) |

A Simple Capacitance Multiplier Power Supply For Class-A Amplifiers - A basic
circuit is provided in the article, but it is assumed that the builder knows all the
pitfalls. The supplied schematic is in fact for a capacitance multiplier filter (not a
regulator), but is somewhat lacking (I feel) and can be improved
dramatically....(added 04/05/06) |
