Interesting unit from European electronics style craftsman and technical design . 75% of this unit is power supply , promotes high attention to quality of voltages power supply generates , detailed components management work on board , good , long lasting components used , power supply shielding is extreme. Even all internal wires insulated from chassis by cork material. Simple schematic in signal path line.
Power supply standard SMPS , in opto-isolator section they use opto coupled transistor instead diode . Two steps voltages transformation and filtration used in this unit . General SMPS Power supply generates – + 14v, – 14v, +9 v , – 9 v .
Minuses – shielded power supply but no ventilation holes at all ( internal heat in small closed box kills capacitors ) , using SMD capacitors (small to save space but not reliable for long term ) .
