DIY SOLID STATE PROJECTS
|
Documented below are a couple very simple Class A DIY power amplifier projects. The projects are very simple, but will require a robust power supply to reduce the potential for hum. If you have a DIY Solid State Project that you would like to share with other audio hobbyists through this site, please contact me.

Jean Hiraga - Le Monstre 8W Class A Amplifier - 12 January 2008 
Dan has put together a great looking amplifier which is based on Jean Hiraga's popular article "Le Monstre" (The Monster). Dan has used the original board layout, transistors and JFETs noted in the article. However, he did make some chages to the power supply. Instead of a battery, Dan's power supply is regulated. |

Class A 2SK2221 Mosfet Amplifier - 4 July 2007 
This is Jochem's first DIY Audio Project, a build of Mark's ZCA shown below. Jochem's build of this very simple Class A Mosfet amplifier uses the 2SK2221 mosfet and a modified heavy duty power supply. Jochem was very pleased with the results of this project and is looking forward to completing more DIY Audio Projects in the future. |

DIY Class A 2SK1058 MOSFET Amplifier - 18 November 2006
Mark has put together a very simple MOSFET amplifier that he fashioned after a single-ended (SE) tube amplifier. The amplifier uses a single MOSFET and the results are a very simple Class A SE amplifier with a low parts count. |
