The Mars SET amplifier is an integrated Single Ended Triode amplifier with about 8 watts per channel music power output. This might sound like a low power amplifier, but you have to experience the sonics of 8 watts of Class A triode power, to realise that this is a very powerful amplifier.The bass response and general power capacity of the KT88, not to mention the plethora of options in current manufacture, makes it an ideal tube for a high power SET output stage. The cathodes are indirectly heated, which facilitates very low levels of noise/hum during operation. The well designed power supply filter section, utilising capacitor-inductor-capacitor (CLC), allows a wide sound stage to be experienced.The care in producing exactly similar output transformers ( one pair manufactured at a time) and the well designed power supply section are probably why. We also take care to construct the stereo amplifiers with exactly the same layout for Left and Right Channel.The KT88’s can be expected to last about 5000 hours, and the preamp tubes closer to 10 000 hours. The rectifier tube can be expected to last many years. Common wisdom suggests replacing the power tubes every second year, and preamp tubes every four years.We manufacture our own transformers, allowing us the ability to go beyond what is available on the open market. Experimenting has shown that size matters a lot, and our designs can reproduce 20Hz. The 114mm sized laminations on a 50mm stack we use on the output transformer, allows the wide bandwidth and low losses you need for dynamic music reproduction.Specifications:8 watt per channel music output250VA power transformer (power consumption is about 100VA)25 watt output transformers with 7% local cathode feedback (24 Henry primary inductance)Each output transformer have 9 sections interleafed for optimal high frequency response25 Kg weight; 420mm wide, 370mm deep and 250mm high2 x Shuguang KT88 triode wired output tubes with cathode bias (any type of KT88 can be supplied on request)Class A operationNOS 5U4G tube rectifierNOS 6SL7GT input tube (grounded cathode)NOS 6BL7GT driver tube (cathode follower)one capacitor in signal path: AV（ARCOTRONICS）0.47UF 850V MKP axial coupling film capacitorzero global feedbackdual-mono power supply with separate PI filters for each channelpolypropylene filter capacitorsAlps RK27 100Kohm stereo potentiometerAll resistors are carbon composition 2 watt types, except high power wirewounds used on cathodes and in power supply.Cathode bypass capacitors are Low ESR audiophile grade electrolytics.point-to-point wiringsilicon covered hookup wire used throughout (500V 180 degrees C).Designed for loudspeakers from 4 to 8 ohm impedance.Welded steel enclosure with black epoxy covering.6 month guarantee on tubes; 2 years on amplifier hardware and components.Shipping worldwide can be arranged.Production capacity: two amplifiers per month. 30 days to deliver from receiving order.
