This is an alternate schematic capture of the Gibson EH-100, Gibson's foundational pre-war electric guitar and lap steel amplifier. The EH-100 was designed primarily for Hawaiian guitar players and early electric guitar enthusiasts in the late 1930s. Its pentode preamp stage and push-pull 6L6 output produce a warm, dark, and naturally compressed tone with excellent sustain — the sonic blueprint that Gibson's amplifier line would refine and build upon through the postwar GA series.
