Welcome to my new web site. I've been neglecting it for a while so I thought a redesign was in order. I've also added new content: a few more amps I've built since the last update.

I put this site up as a resource for beginners. While building guitar amps is a rewarding hobby, it is often daunting. Getting the first amp built and working correctly can be quite a challenge, especially for someone with no background in building electronics. The hardest part of getting into amp building is building the first amp. It takes a combination of having all the necessary tools and all of the required parts. Nothing is as frustrating as trying to build an amp without the right tools, or to be missing a necessary part to finish up the amp.

I would like to thank Edward T. Dell, Jr., Editor and Publisher of AudioXpress Magazine, who has kindly granted me permission to use both the "Remaking of a Champ" and "A Western/Russian Tube Chart" originally printed in Glass Audio Magazine. Audio Xpress is a fine publication and although it deals mainly with hifi circuits, it is a tremendous resource; I would encourage anyone interested to subscribe.
