Guitar Amplifier Projects

Champ Project

This page documents a guitar amplifier project I completed in 2011. It works and sounds great; it has served my primary amp that I play at home for over a year now. I might cover the cabinet; I might not. I've also thought about just painting it in a glossy color.

The basic design (schematic, layout) is that of a Fender Champ 5F1. It uses a 12AX7 for the preamplifier section and a 6V6GT for the power amplifier section in a cascaded Class A configuration. I also decided to keep the original tube power supply (using a 5Y3GT rectifier).


If you are trying to do a project similar to this and want some advice, let me know and I'd be glad to help in any way I can! >> projects
