February 7, by Paul J. Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators.
The spreadsheets are in standard Excel format, and should work in just about any spreadsheet program. Each ajdioxpress has two main pages: This article was published in audioXpress, March December 13, by Gregory L.
Charvat, two pre-amplifiers are used with a battery powered high voltage supply. The high voltage supply works by creating a square wave with a timer. The square wave is fed into a small audio power op-amp. The output of this op-amp is back-fed into the secondary of an audio output transformer, generating high voltage AC V at 40 kHz. This signal is rectified, filtered, and regulated in a conventional audioxpresd.
The entire system runs on 8 AA batteries and should operate for approximately 4 hours continuously.

Getting the Most from THAT’s Balanced Line Drivers and Receivers
This is not surprising. The Mighty Mouse is indeed a good sounding and inexpensive project that is also a good introduction to tube amplification.
A pot with 64 levels and precision metal film audioxress that is hard to beat for sound or facility, as he describes it. The project started with a clean sheet, looking to address potentiometer design with a quality that rivaled existing designs while maintaining a reasonable cost.
