AX84 Lead II Tube Guitar Amplifier Projects - by Brian Schmittling

[All Lead II Projects] [All Associate Projects] [All Projects]


Project description goes here...

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

NOTE:  New builders should NOT attempt these projects as a first build.  All of these amp designs are VERY sensitive to layout and lead-dress.  If you don't have several builds under your belt prior to attempting one of the projects, you are NOT likely to succeed without extensive debugging, if at all.  You have been warned.

Before using these materials, please read our terms and conditions.

Brian's Lead II Lite Current Materials

The L2L is a medium distortion amp that takes the HO and SEL to the next level. It has more gain and distortion than either but can clean up with the guitar's volume even with the gains dimed. It offers a wide range of tones from clean to metal and is very touch sensitive.  The L2L SE is a modification that can be adapted to either the High Octane or the SEL amps just by adding a couple of terminal strips and doing a bit of rewiring and component changing.  The Lead II Lite ~ Club is a 20W push-pull amp.

Brian's Lead II Lite SE

Lead II Lite SE 09.11.24
This is the 20W Single-ended version of the Lead II Lite based on the SEL poweramp.  Note: The current power tube is a EL34 that will be replaced shortly by the standard KT88.

"L2L preamp mated with an AX84 SEL EL34 poweramp using a Gibson Les Paul Studio, 498T bridge PU, Mesa oversized 4x12 with Celestion G12T-75's, mic'ed with one Shure SM57 two inches from the speaker, aimed straight at the edge of the dust cover, into a Presonus Firebox, using Cubase SX3 with a little bass and high mid boost, doubled for her pleasure.

G1=11   G2=11   TR=5/6   MD=4/5   BS=7/8   MV=3/4

I LOVE the sound of this amp.  The more I play it, the more I think I will only be disappointed in a higher gain version.  Everything just sits right where it should tone-wise.  I can't say it enough, thanks for the help and thanks for designing my dream amp.
