First produced in 2001 our Stereo 40 amplifier has a tradition in the UK of quality, value and reliability. Having obtained several highly praised reviews in the British hi fi press, there are thousands of happy owners in the UK, Europe and USA. And our handmade construction means they will last a long time, keeping their value. The new MK III version pictured here has all the features of the best high end amplifiers at a very reasonable price.

Key features that a good valve amplifier should have:

A Valve Rectifier (centre valve) gives a very smooth sound, normally only fitted to expensive amplifiers. We use the excellent 274B WE design.

Choke Regulated Power Supply. Working in conjunction 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. We believe our large handmade output transformers to be amongst the finest available. They are more expensive and difficult to make, but worth the effort.

Low Feedback. Too much feedback can spoil the sound of an amplifier. We only use a small amount in the Stereo 40 MKIII.

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 (or even KT66/77, 6CA7, 6550). So you can experiment in the future.

Ultralinear or Triode?
For sixty 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 amplifiers in one! Most hi fi fans prefer the sound of triode valves, especially for acoustic music.

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. Try the new Tianjin “Full Music” or SG “Treasure” types or Vintage USA/Russian types.

Remote Control
It’s hard to get exactly the right volume in your listening position. Now you can make fine adjustments in your arm chair, to get a precisely the right sound level.

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 10mm solid alloy front panel with polished dark chrome alloy knobs. And our famous Plexiglas valve cover to create a stunning visual impression.   On the scales at 25Kg this amplifier is 9Kg heavier than the ST40 MK I.  No lightweight in quality or performance a true “high end amplifier” at a low price.  We can offer a range of upgrades including Shuguang “Treasure” valves and Russian types.  As well as the superb Jensen “oil in paper” capacitors.
