AX84 Single Ended Lead Tube Guitar Amplifier Project

[classic projects] [current version] [old versions]

Overview

The SEL is like a juiced up rock and roll amp from the 80's... only smaller. Like a Hi-Octane but with more power. Like a P1-eXtreme, but meaner. This is a good choice for someone who wants more distortion and has built an amp or two before.

Tone goes from cleanish to semi-saturated distortion, depending on gain settings and guitar volume setup. Responds well to pedals and retains your guitars tone.

Features

  • Hi-Gain 12ax7 Preamp
  • KT88/KT77/KT66/EL34/6L6/6V6 Power Tube in Class-A Single Ended Configuration provides a range of output wattage selections.
  • Cathode-follower driven Bass, Mid and Treble tone controls allow you to shape your sound. Alter the values of the components in the tone stack to tailor your sound.

Skill Level: intermediate --- Status: Ready to Build.
