Item Description Technics SU-V9 125,000 (Launched in 1981) Equipped with a super base control that boosts only the very low frequency range, the speaker's frequency characteristics can be expanded by approximately 1 octave to the low frequency range with a sharp rise of 12 dB/octave and a shelving tone with a maximum boost of 10 dB. In the Phono input 1, in addition to the switching of MM and MC, it is equipped with 2 stages each of 1 mV/2.5 mV and 100 μV/250 μV, a total of 4 stages of input sensitivity switching. The input impedance is set to 47 kΩ for MM and 100 Ω/220 Ω for MC. An automatic load detection servo power supply is used for the power supply.This servo power supply greatly improves the response of the power supply by controlling the conduction angle at the same time as rectification through four SCRs that are bridged with a voltage detection circuit. This eliminates voltage fluctuations due to fluctuations on the primary side and large current consumption in the output stage, and successfully supplies stable voltage to all stages including the output stage.In addition, it has a low impedance of 1/10 compared to conventional products, and is highly regulated even though it has 10 times the power supply.Furthermore, this servo power supply is equipped with a load impedance detection and a tap switching circuit that detects the combined impedance of the speakers connected to the speaker terminals immediately after the power supply is turned on. The high voltage or low voltage taps of the transformer winding are automatically selected and the same rated output is guaranteed whether the impedance of the speakers is 8 Ω or 4 Ω. Inspected, maintained and adjusted. This is a beautiful product with few scratches and stains.
