AFON 20 Valve Combo Amplifier

The valve amplifier reinvented - Built for tone purists who demand the best.

Not a replica - a woodfield.

What makes our amplifiers unique?

Modern construction techniques applied in a traditional setting

  • Stringent Faraday caging to prevent any unwanted external electromagnetic interference (especially on a busy stage or studio)  
  • High-quality mains IEC inlet/outlet filtering system, complies with IEC/EN 60601-1
  • Silicon Diode Rectification methods for high attack capabilities
  • Solid Busbar and Turret construction for longevity and reliability
  • High quality, modern componentry - minimum 20% over spec for longevity and reliability
  • Quality, robust valve base mountings and retainers for solid installation and reduction in induced microphonics
  • Optimised, bespoke manufactured mains/output transformers for reduced weight and Eddy-Currents/unwanted Tx characteristics
  • Use of highest-grade aviation specification wire and looming techniques throughout the entire build in order to prevent noise induction between looming
  • High-grade laser-cut steel chassis and powder coating for longevity
  • Harma vintage valves, balanced preamp and output pairs

Exceptional build quality

  • Ergonomic, sleek, and robust control knobs and switches
  • Quality leatherwork for handles and corner protection
  • Customisable panelling and quality tolex covering
  • Robust 12mm Latvian Birch ply cabinet
  • Meticulously hand-soldered turret board construction
  • Solid build to prevent any unwanted microphonics or rattles

Extreme versatility

  • Tonally versatile through the use of a Power Selection Variable HT (B+), Master Volume, HI and LO inputs with both Single-Ended and Push-Pull options. These allow for a wide variety of tones at any volume level.
  • Lightweight construction, allows for easy transportation and usage anywhere.

About the AFON 20:

Woodfield takes the timeless magic of valve technology and reimagines it for the modern guitarist. This isn't another clone, reissue or replica - It's a future classic crafted for players who want the soul of analogue with the perfomance capabilities of modern technology.

The AFON 20 is a versatile 20 Watt RMS combo valve amplifier, excelling at either wonderfully clean or crunchy, dirty tones at very low "bedroom volumes"... or as a punchy stage amp when cranked right up. With so many tonal sweet spots to discover, it is the perfect amplifier for the discerning musician.
