The Tremolux 6G9-D is a brown-panel Tremolux variant from approximately 1961–1963, producing around 14–15 watts from a pair of 6V6 tubes into a single 12" speaker. The brown-era Tremolux added a dedicated vibrato channel alongside the normal channel, with a neatly voiced tremolo oscillator that gives a smooth, rhythmic depth effect. The 6G9-D represents a subtle revision within the brown-panel production run. These amps are prized for their warm, touch-sensitive clean tone and musical tremolo that is less choppy than later optical designs.
