Maintained! A rare power amplifier with a lot of luxury! This is the last model equipped with a power MOS-FET that Sansui is good at. Mid-high range with stable driving power and fine particle feeling unique to MOS. It is an extremely complete masterpiece amplifier that combines resolution, core thickness, and ease of listening. There are scratches on the top surface and stains on the front panel (Yoichi Murakoshi)
Maintenance information: 2022.4.13 Maintenance (INPUT switch disassembly contact polishing. Speaker relay bad contact replacement. Protector transistor deterioration replacement Semi-fixed volume deterioration replacement for power amplifier adjustment. Solder correction of the main parts of the electric source board and power amplifier board. DC balance, bias current adjustment.)
Accessories: Instruction manual
Main specifications: 110W+110W (8Ω) 150W+150W (6Ω) Size W460 × H174 × D480mm Weight 37kg
Maintained! A separate power amplifier from Sansui that has an excellent sense of volume and driving power in the low frequencies. It is a masterpiece created by putting in the highest quantity of materials at the time. It's a low frequency with a sense of scale that can't be heard with amplifiers these days, and JBL's 4343 class speakers can drive with plenty of room. A feeling of use such as rust, abrasions, and dullness can be seen on the exterior and terminals (Kobayashi Hitoshi)
Maintenance information: 2023.5.24 Maintained (input changeover switch disassembly contact polishing, LEVEL switch x 4 disassembly contact polishing. Speaker relay replacement. Flat amplifier and power amplifier built-in constant current diode replacement. Semi-fixed volume replacement for power amplifier adjustment. (Overall adjustment)
Accessories: instruction manual
Main specifications: with balanced input, digital meter effective output 300W+300W (8Ω) 880W+880W (2Ω) W474 x H215 x D498 mm 36 kg
Replaced deteriorated parts and refreshed! A power amplifier with an eye-catching black and large power meter typical of Sansui. It entertains me with the powerful feeling that can be felt from the appearance and the sound quality that stretches and stretches supple (Fujisawa Koshi)
Maintenance Information: 2022.1.20 Maintained (first stage FET, electrolytic capacitor, black film, semi-fixed resistor, rectifier diode, heat dissipation sheet for power transmission, cement resistor, fuse resistor, temperature guarantee Replace Varistor, SP Relay, SP Terminal, Lamp, Fuse, EI Connector SP selector switch, gain VOL disassembly cleaning Circuit adjustment, input/output waveform confirmation, meter adjustment, load test (1kHz sine wave, 8Ω load: 110W+110W, OK), sound test.)
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 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
Main specifications: 300W+300W (8Ω) W474 x H215 x D498 mm 36 kg
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)
