Main Specifications: DSP Internal Parametric Tone Control Non-Contact VCA Volume W475×H177 × D442mm 25kg
MAINTENANCE! Yamaha's masterpiece preamp. It is a model that has a reputation for phono and is still popular from analog users. The natural and transparent Yamaha sound allows you to fully enjoy the charm of acoustic instruments such as the touch of the piano, the feeling of attack, and the cleavage of the strings of the guitar. Scratches on the top plate and so on. Serial 07094 (Atsushi Takasaki)
Maintenance information: 2021.1.14 Maintenance completed (micro SW, heat dissipation sheet, fuse, semi-fixed resistor, capacitor, transistor replacement. Resoldering of all boards, all VR, SW disassembly cleaning. (Check voltage, input and output waveforms, check left and right balance, and perform a comprehensive operation test by connecting a power amplifier to confirm normal operation)
Accessories: copy of the document
Main specifications: PHONO × 3 (MM/MC) MC head amplifier built-in W435 × H72 × D320 mm 7.9kg
Full overhauled in November 2012! The transparency and three-dimensional sense of sound are brilliantly revived. It is one of the recommended ones for those who prefer natural and crisp sound in the middle and high range. In particular, the quality of the PHONO input is outstanding. The appearance has dullness and stain stains. Serial 03061 (Wataru Sato)
Maintenance information: 2020.1.25 Maintenance (balance volume contact cleaning, each amplifier offset adjustment, other switches, volume contact cleaning, check each input and output operation) 2012.11.25 Maintenance (The condition of each component was checked and electrolytic capacitors and transistors were replaced with new products. Contact cleaning of each volume and switch, and resolder the degraded part of the solder surface of the substrate. I checked the input/output waveform, left and right balance check, and a comprehensive operation test by connecting a power amplifier to confirm that it works without any abnormalities.)

The price has been reduced. 2023/6/9 sales price 49,800 yen A control amplifier that inherits the sound of Yamaha's famous C2a. A highly reliable phono equalizer is used, so you can enjoy both MM/MC. It has a clean sound typical of Yamaha, and it makes the outline of the sound clear. The exterior has dullness and insulator marks. Serial E052015 SU (Yonejima Satoshi)
Maintenance Information: 2023.6.9 Operation confirmed
Accessories: copy of instruction manual
Main specifications: 3 line inputs, 3 tape terminals, 1 phono input system (MM/MC), W438 x H86 x D405 mm, 8.8 kg
The price has been drastically reduced! 2023/6/17 sales price 99,800 yen ※The remote control is out of stock. Maintained! It is a control amplifier that supports digital input in addition to analog input. The simple mechanical design is also good. The sound quality is also attractive, with a relaxed, highly transparent sound typical of Yamaha. The exterior is dull and there are small scratches on the top plate. Serial E024630RT (Yonejima Satoshi)
Maintenance information: 2023.6.17 Maintained (input circuit, power circuit, preamp circuit, all circuit boards were soldered and fixed. Volume contact correction. Input/output pin jack polish (Close the main volume screw, and the volume volume of this unit comes with a motor, so it doesn't feel like a normal amplifier, but it's a specification)
Accessories: There are no accessories
Main specifications: 8 digital inputs, PHONO (MM/MC), 18-bit operation, built-in twin D/A converter, W473 x H130 x D400 mm, 12.2 kg
We have drastically reduced the price! 2021/9/30 selling price 39,800 yen* There are oxidation and unevenities overall. Maintained! A preamplifier with a lot of phono that is great for analog users. The PHONO has 3 inputs, 5 levels of MM cartridge load, and the MC head amplifier uses a dedicated transistor, so you can enjoy clear, crisp sound with a certain outline. The appearance was painted on the top plate, but the deterioration is noticeable. Serial 05627
