Our pursuit for making better amplifiers often leads us to places that no one has been before. Here is such an example. The magnificent Russian GU81 has superb audio qualities and is tremendously robust. We were so inspired by the prototype we decided to have a limited edition production in response to customer requests.
New MB81 SE !
The Ultimate SET Amplifier!
The sonic qualities of the magnificent GU81m valve make it the ideal candidate for those seeking a high power Single Ended Triode amplifier. Its 100 watts of power make it ideal for low to medium efficiency speakers in medium to very large rooms and will give outstanding results.
110w of Pure Triode Power. For over 80 years this fabulous valve has reigned supreme in the field of audio. Designed by RCA with only slide rules, no computers at that time! Never bettered* and still in production it is an absolute for those that like a big warm detailed sound. The 845s Achilles heel is the demands it makes on the amplifier built around it.
In our quest to make the best kinds of valve amplifier it is logical that we should use the 1930 RCA big triode as it is in many ways like a jumbo 300B having very linear characteristics and a sublime sound. But it requires a huge voltage swing to drive it to full power (440v), a massive power supply, a very special driving circuit and exceptional output transformers.
50 Watts of beautiful sound.Designed in Leicester by David Shaw, founder of Icon Audio. The 805 valve is very special and is capable of making golden sublime music. But this requires the best driving circuit and power supply. We have used all experience to create the MB805 amplifier which gets the very best out of this valve.
Super KT 90’s or KT120’s in Parallel Push Pull. Designed in Leicester by David Shaw, founder of Icon Audio. Following on the heels of our acclaimed MB845s, our new MB150s are a 3 stage design, the front end is inspired by the Leak “TL” designs. We have used the older bigger 6SN7 driver valves from the early 1940’s. These have a reputation for a richer more textured sound, reliability, and a very long life. This combination of traditional design, excellent valves, audiophile components, hard wired, no printed circuit boards, custom wound transformers, massive choke regulated power supply. With beautiful looks all add up to a stunning combination!
The new Tung Sol KT120 valve seems to have taken the Hi Fi world by storm! Taking the crown as the King of pentodes from GECs 1957 KT88. Icon Audio’s upgraded version of our KT120 power amplifier has several improvements including circuit and cosmetic improvements. Most importantly a built in bias meter greatly simplifies keeping your amplifier in peak performance. Previously you had to pay attention to numbers. Now if the pointer is on the black mark, it’s correct. Very easy!
A Versatile Affordable SE Solution! The MB30SE is a versatile high quality very simple mono block amplifier for Full Range and medium sensitivity speakers. Using only 2 audio valves it has excellent bandwidth with the best qualities of SE* without the disadvantages of flabby bass, hum and low power that many designs suffer.
