Maintenance has been completed, such as replacing 21 capacitors, volume, balance volume, disassembling each selector, polishing the contacts, and applying selector contacts! A masterpiece preamp that can be said to be the culmination of the C-200 series! This model has reduced the roughness of the sound and stands out for its subtlety. The sound quality is straightforward and clear, and it successfully adds Accuphase sound quality to any system. Equipped with an MC head amplifier, it is possible to play back high quality records. There are threads and dullness on the exterior, but considering the model year, it's good enough (Mizusaki Ryo)
Maintenance information: 2026.6.15 Maintained (replaced due to a film capacitor problem in the MM phono circuit on the right side. I will replace it due to a resistance failure in the MC circuit. Since the solder on the ground part of the phono circuit is broken, I will fix it by soldering it. No symptoms were confirmed regarding the right channel not appearing. Electrolytic capacitors with large capacity changes (± 20% or more) are replaced, volume, balance volume, disassembled for each selector, contact polishing, and contact grease is applied to the selector contacts. We will clean the panel, knobs, housing, and terminals. (Other aging tests were performed)
