Power Amplifiers

100Wrms per channel – 180 Wpeak in pure class A with very low distortion
4 Ohm and 8 Ohm selectable impedance at the output
NO capacitors on the signal path
minimalist design with a minimum number of active components: voltage stage made with only one tube in push-pull configuration followed by the output current stage made with only a pair of AUDIO MOSFETs in push-pull configuration, transformer output for impedance matching
output current stage with buffer configuration
NO Global Feedback
microprocessor supervision
huge power supply with 1900Wrms of reservoir power in dual-mono configuration, massive inductive filter and high current capacitors, soft start at power on
massive aluminum and stainless-steel cabinets: 21Kg the amplifier and 39Kg the power supply

60Wrms per channel – 140Vpeak in pure class A with very low distortion
NO capacitors on the signal path
minimalist design with a minimum number of active components: voltage stage made with only one tube in push-pull configuration followed by the output current stage made with only a pair of AUDIO MOSFETs in push-pull configuration, transformer output for impedance matching
output current stage with buffer configuration
NO Global Feedback
Audio Grade Hybrid Switching Mode Power Supply, 600W reservoir power, high current capacitors, soft start at power on
massive aluminum and stainless-steel cabinets: 21Kg the amplifier and 10Kg the power supply
