After receiving many requests for info about my circuits and designs I decided to put the site back up. I don't have much time to dedicate to audio at this time so won't be able to answer many questions. Over time I hope to add some info that may be of use to hobbyist's. No CCS circuit boards are available for sale at this time.

The Tabor amplifier

Just a few things to take care of. All schematics and designs are copyright 2001-2008 Gary Pimm. All rights reserved.

WARNING!! Tube circuits contain high voltages and are dangerous to work on! Do not attempt to build any of these designs of you are not qualified. The author is not responsible for personal injury or property damage caused by use of the information on these pages.

The C4S circuit presented in some schematics is available in kit form with a great manual from the fine folks at Bottlehead Corporation http://www.bottlehead.com

The high voltage/high current C4S shown in the SE45 schematics is Voltsecond's design with more information at  http://www.siteswithstyle.com/VoltSecond/
