The Worlds First KT150 Power Amplifier For The New Tung Sol KT150 Valve

Getting the best out of this super new valve
One of their best-selling power amplifiers offering excellent all round value in terms of power, quality and specification. Designed around the superb new Tung Sol KT150 or KT120. Our specially designed LDT transformers get the best out of both valves. As a “modern” design it is at the cutting edge of what is possible from high end valve amplifiers. In this case a heavy duty individual power supply. The venerable “Leak” inspired driver circuit updated to match the performance of the KT150 and our in-house designed output transformers with our unique design of Tertiary (balanced) windings. The hi fi press has been unanimous with praise for the MB90 and ST60 (integrated) design. 

Designed for modern less efficient speakers this amplifier gives a fast yet very smooth musical quality to the high power available, making them very versatile in their application. 

Pure Triode mode has equal emphasis here. Customer feedback indicates that 80% of customers listen to Triode mode most of the time. The sonic characteristics of the KT150 are a little fluid and warmer when used in this way. The MB90 is a very cost effective way of getting a large 60 watts Triode output without the expense of large Triode valves. This is an ideal replacement for a larger transistor amplifier for someone wanting a more easy listening presentation.

The combination of medium/low feedback, Triode/UL and 4/8 ohms output means that a wide range of pre-amps, speakers and room conditions may be accommodated.
