Vacuum Tube Amplifier Basics
This project is to see if a four-watt-per-channel amplifier using 6SN7s as output tubes is practical.
6SN7 Amplifier Project
This current version of the book includes technical information from previous versions plus a more detailed example of amplifier design and assembly. Using a concise format, 110 reference pages cover technical information that pertains to vacuum tube circuits. Design examples take you through the steps of fabricating a traditional chassis layout and designing a Class A stereo amplifier (pictured on the book cover).
The file download version of the book Vacuum Tube Amplifier Basics has a price reduction of 50% for the month of July, 2025.
Using sound pressure levels to determine amplifier output wattage that produces audio levels below ear-damaging levels.
