Icon Audio Stereo 40 MkIII M Integrated Valve Amplifier

Available in two versions:

- Integrated EL34 40/20W Built-In Bias Meter

- Integrated KT88 45/20W Built-In Bias Meter 

Icon Audios best value mid priced amplifier. We believe the ST40IIIM ticks all the boxes that a good amplifier should have! Now with built "Easy Bias" meter to keep your amplifier "On Song". Having obtained several highly praised reviews in the British European Hi Fi press, there are thousands of happy owners in the UK, Europe and USA and their handmade construction means they will last a long time, keeping their value, while it's worldwide popularity keeps the price down.

Key Features

- Valve Rectifier (Centre Valve): Gives a very smooth sound, normally only fitted to expensive amplifier. Icon Audio use the excellent 274B WE design.

- Choke Regulated Power Supply: Working with the valve rectifier the large choke gives super-smooth power regulation for a silent background.

- Tertiary Transformers: Have an extra (third) winding which reduces distortion, using less feedback. Icon Audios large handmade output transformers are among the finest available. They are more expensive and difficult to make, but worth the effort.

- Low Feedback: Too much feedback takes the spark and spontaneity from the sound of ST40 IIIm

- Wide Range of Valves: The Stereo 40 is designed to work with a wide range of output valves. You can choose between EL34 or KT88 so you can experiment in the future and get the sound that is best for you. 

- Ultralinear or Triode?: For over 60 years Hi Fi fans have argued which sound is better. With the Stereo 40 III you have the choice of both at the flick of a switch. It is like having two amplifier in one.

- 6SN7 and 6SL7: Far better than their miniature cousins, these larger older valves are the best in their class for their musical sound and longer life. 

- Plenty of Power: 40 watts of power is enough to fill a medium to large room with a high volume of musical excellence. 

This new design is finished with a fine metallic paint work that is easy to clean and is wear resistant. A 10 mm solid alloy front panel with polished dark chrome alloy knobs. And our famous Plexiglas valve cover to create a stunning visual impression.
