Afterglow Duette Stereo 6V6 Amplifier Head

£3,490.00

A handbuilt stereo tube amplifier head inspired by the spacious, expressive tones of classic American amplifiers.

Duette combines the warmth and clarity of 6V6 power stages with the depth and dimensionality of true stereo operation. Responsive and articulate, it rewards a light touch, yet blooms naturally into rich, expressive overdrive when pushed.

Paired with a stereo speaker cabinet, Duette reveals its full character, creating an expansive soundstage where reverb, tremolo and stereo effects can develop naturally. The result is a playing experience that feels immersive, dynamic and deeply connected to the instrument.

Available with or without Spring Reverb. For customers selecting the reverb option, Duette is designed to partner with an Afterglow stereo speaker cabinet, which houses the reverb tank and associated connections as an integral part of the design.

An inspiring, immersive amplifier built for players who listen as much as they play.

  • Fully Discrete Stereo Signal Path – Separate cathodyne phase inverters and output transformers per channel.

  • Bias-Modulated Stereo Tremolo – Independent bias modulation per side for true panning tremolo, switchable in/out of phase.

  • 18W + 18W Output – Dual 6V6 push-pull power sections deliver rich breakup and clean headroom.

  • Buffered Stereo FX Loop – Tube-buffered mono input / stereo return loop with adjustable send level.

  • Optional Tube-Driven Spring Reverb – ECL82 pentode-driven tank with dedicated ECC83 triode recovery stage.

  • Premium Signal Path Components – SoZo NexGen Blue, Mallory 150, and silver mica caps for refined, musical response.

  • Selectable Global Negative Feedback – Switchable NFB circuit offers a choice between harmonic openness and tighter control.
