Icon Audio Stereo 40 Mkiv Kt66 Remote Integrated Amplifier B Grade Half Price

  

Exceptional performance at a budget price! Stereo 40 MK IV 6L6 is a simplified version of more expensive KT88 version.

The design and construction remains the same with slightly lower power. THIS "B GRADE" MODEL IS A BRAND NEW TECHNICALLY PERFECT MODEL WITH MINOR COSMETIC FLAWS. This model has remote control.

Designed in Leicester by David Shaw, hand built using only "point to point" wiring without the cheaper Printed Circuit Boards, using full sized audiophile components. Having power enough to drive almost any loudspeaker also having "Pure Triode" option for those preferring a "warmer" presentation. Icon Audio amplifiers are made to be easily serviced, and our dedicated service centre in Leicester are here to help. The Stereo 40 MKI was our first model in 2001 and has always been a special product to us.

Since that time we have substantially improved it over the years. Not just another "budget" amplifier!

We took a long hard look at our award winning Stereo 40 MKIV to see where cost savings could be made without sacrificing any quality. Firstly, we removed all non-essential features like "standby" and "headphone" etc which have no impact on audio quality. Secondly the excellent 6L6/KT66 group of valves are more than 50% cheaper than the KT88/EL34 types with only a relatively small loss in power (30+30W UL). Thirdly the lower power requirements of the 6L6/KT66 means a saving in the amount of transformer copper and iron used and power consumption. In summary the ST40 6L6 has all the performance and quality of the ST40 MKIV using exactly the same circuit and chassis at a considerable cost saving.

In line with our other amplifiers there are many valve and capacitor upgrade options like the Genalex KT66 and Tung Sol 6L6 ask for a quote. In common with the ST40, ST60 and ST300 the David Shaw designed Cascode circuit uses the 6SN7 driver valve, probably the best sounding audio valve ever made! This means that there are only two types of valves used with the obvious benefits for the owner. Key to astonishing performance of the ST40 6L6 are the handmade output transformers which have helped win us so many awards. The ST40 6L6 transformers stay faithful to the original formula with the low distortion tertiary winding almost unique in modern amplifiers.

Designed and manufactured in house Tertiary Wound means they have an extra (third) winding which reduces distortion, allowing the use of using less global feedback. Working in conjunction with the smoothing capacitors the large choke gives super-smooth power regulation for a silent background.

Too much feedback can spoil the sound of an amplifier. We only use a moderate amount in the Stereo 40 6L6.

The lower cost forerunners of the KT88 and still considered by many to be amongst the finest Beam Pentode valves ever created, efficient, easy to drive with low distortion the Stereo 40 6L6 is designed to get the best out of this valve in big dynamics and micro detail. In tests 30 watts is more than ample for a medium to large sized room with average efficiency loudspeakers.

And now with several speaker manufacturers such as Klipsch making 100dB "Heritage" designs requiring only very modest power, very high sound levels and deep bass are possible. On request at no extra charge we can convert to pure triode operation. Remote control of volume with mute facility is available as an option ask for a price.
