Accessories: None
Main specifications: Left and right independent 2 power supply system Diamond differential circuit Effective output 110W+110W (8Ω) Load impedance 4-16Ω W482 × H187 × D450mm 20.3kg
The price was significantly reduced. 2021/10/23 Selling price 148,000 yen A power amplifier with a low frequency of ringing is a masterpiece. The power supply unit uses a left/right independent two-winding toroidal transformer, and a high-capacity silicon rectifier and a large capacity electrolytic capacitor constitute a powerful power supply. I get the feeling of bouncing the piano system and the saxophone approaching from below. Please experience this feeling by all means. Serial 246120957 (Hirotsugu Kondo)

Big discount! (original price: 198,000JPY [tax inclusive price])
Very rare amplifier. The sound is very punch but finely detailed at the same time. The expression of fading sound is especially amazing.
*There is some pot on the volume knobs.
*2016.6.22. - Maintenance completed (Cleaning of input selector switch, replacement of relay, and protector capacitors, re-soldering of main parts on power amp/AC circuit, and overall adjustment)
The price has been reduced! 2023/6/17 Sales price 130,000 yen*Inexpensive because the exterior is in poor condition. Maintained! The younger brother of the B-2301L, which is rarely in stock. It inherits the character of a powerful advanced aircraft, and shows performance that exceeds the price with good extrusion, good response, and strong mid and low frequencies. On the exterior, damage such as noticeable scratches on the top plate and curled sidewood is conspicuous. Serial 2150023 (Satoshi Yonejima)
Maintenance information: 2023.6.17 Maintained (relay replacement. Power amplifier built-in current diode replacement. Semi-fixed volume replacement for power amplifier adjustment. Meter lamp replacement. Input changeover switch x 5 disassembly contact polishing. Fix it by removing the input pin jack mounting base jack. DC balance, idling current adjustment)
Accessories: no accessories

Disposal prices have been reduced! (Member discounts are not applicable) 2022/6/23 sales price 128,000 yen maintenance completed! An eye-catching power amplifier with Sansui's characteristic black and large power meter. It entertains me with the powerfulness that can be felt from the way it looks, and the supple, stretchy sound quality. The exterior has dullness, scratches, rust, etc. over time.
