Hand Wired Guitar Amplifiers
I have been playing guitar for about two years. I’ve been an electronics technician for nearly 30 years. I’ve decided to mix my love of music and electronics and build my own amplifiers.
I work primarily with surface mount electronics under high magnification at work. Building tube (valve) amplifiers is truly a relaxing pastime. You will note that a couple of prototypes utilize a bread tin for the chassis.
The Sonic MA1 and All American Four are based on designs from the book, “Building Vacuum Tube Guitar & Bass Amplifiers, Volume 1” by Tino Zottola.

Sonic MA1
The sonic MA1 is a 1950’s design utilizing a 12AX7 preamp and a 50L6 power stage. This amplifier also utilizes a solid state rectifier and an isolation power transformer for safety. Undistorted power output is about 3 watts. Click on the photo for more information.
All American Four
The All American Four gets its name from its tube lineup - 12AT6 (x2) preamp, 50C5 power amp, and a 35W4 rectifier. These are the same tubes as the broadcast radios of the 1950s, manufactured by the millions. The radios were referred to as “All American Five” for their tube lineup. This amplifier shares that lineage. Undistorted power output is about 3 watts. Click on the photo for more information.
