Tube Input Stage The entire input amplification section is based on carefully selected 6SN7 tubes, operating in class-A. It is designed as a symmetrical differential amplifier exploiting an all-valve cascode circuit. This results in a very harmonious sonic image, and instills the musical and tonal advantages of tube technology into the sound character of the M 40 HV. Class-A Output The voltage amplifier stage is an HV (High Voltage) J-FET amplifier circuit with triode performance characteristics, which also operates in pure Class-A mode. The result is excellent bandwidth and an agile performance which defines the sound qualities of the amplifier as a whole. The input to the power amp stage is based on MOSFET driver transistors whose performance curve harmonizes superbly with the HV voltage amplifier stage. At the output side the current amplifiers are equipped with no fewer than twenty extremely high-performance ring emitter bipolar transistors. These components satisfy the most extreme demands in terms of current supply capacity and bandwidth. Specifications Power Output (8, 4 Ohm): 550 W, 1,000 W Dimensions (HWD): 22" x 14" x 18.5" Weight: 115 lb. (52 kg)
