This is a top-of-the-line integrated amplifier that is the culmination of Sansui's technology and Sansui sound. Its sound has a unique brilliance and cuts sharply. It is in excellent condition after the following overhaul: The selector, etc., have been disassembled and cleaned to a sparkling condition. It is one of several amplifiers I own, and the power-on time after the overhaul is about 200 hours. I wanted to keep this amplifier, and I used it occasionally, but I would like to entrust it to the next owner for my life's work. 【Overhaul Contents】 ● Electrolytic capacitor replacement ● Disassembly and cleaning of each selector push switch ● Disassembly and cleaning of the speaker selector ● Relay disassembly and cleaning ● Heat sink cleaning and reapplication of grease ● Moisture-proofing treatment of the circuit board ● Idle current (bias current) adjustment ● DC offset (direct current leakage) adjustment ● Tune-up with other high-quality sound parts ● Replacement of other deteriorated parts #音のおっさんオーディオショップ ◀️ Entrance is here 【Please note】 ● The title may contain search keywords. ● To prevent trouble, we will not respond to price negotiations. ● The shipping method may be changed without notice.
