It has been a few years since I put this page together. I can't say enough about the folks at the AX 84 project and AMPAGE

This is the first AX84 I built using the rev 11 schematic

Here's a cleaner sounding version

This is the second version of my November project. Since I am famous for using creative ways to build things, I built the circuit board out of two pieces of black Formica counter top material. The pins are copper clad brads that I pushed through holes I drilled through the board. I then cut them to length with cutting pliers (they used to be called "dykes" in the pre-politically correct world). The amp has a modified preamp circuit and power unit. I have since stopped using brads and now use eyelets

I've built a fair number of amps in the last couple years and have developed a design that suits my personal taste. This is a combination of ideas from several different types of amp, and also from a design developed by Bruce Collins at Mission Amps in Colorado. Bruce has been extremely helpful in my education.

I'm now in the process of putting together a book for do-it-yourselfers. I hope to make it easier for others who would like to learn how to build their own amps. I'll keep the page updated as it progresses Here's a tube substitution chart I got from Gerald Weber's Column in the April 2001 issue of Vintage Guitar.
