We, the members of the Glowbugs e-mail list, are offering these pages as a printable archive of electronic circuits which use vacuum-tubes to the Radio Amateur and others who enjoy using tubes.

We hope that the circuits, stories, and links found here will encourage you to BUILD and USE vacuum-tube circuits.

We have organized these circuits into general catagories, i.e. Receiver Circuits, Transmitter Circuits, VFO Circuits, etc., and will probably further sub-divide these catagories as time permits.

All circuits and articles taken from ARRL sources are used WITH PERMISSION of the ARRL.

Please click here for our disclaimer and other information on copyrighted information.

If you have any suggestions to make these pages more suitable for your interests, or would like some favorite circuit posted here, please e-mail me, Kenneth G. Gordon, W7EKB by posting an e-mail to kgordon2006 "at" verizon "dot" net.
