Description
SONY Sony Corporation ? CDP-557ESD Condition. The following maintenance has been performed, so the tray opens and closes smoothly and playback functions normally without any problems. There is no problem with skip playback. The remote control is responding normally. Electrolytic capacitors in a part of the power supply section and the audio section board have been replaced with Nichicons KZ, FG, ES, and KW series, which are well known for their high-end audio applications. Electrolytic capacitors are parts that wear out rapidly, so even if sound is coming out normally, they can cause sound degradation and noise. Replacement is necessary after a certain number of years. The bass sound has become thicker and very rich. The G chassis used in the 555ESD was not used in this model, but the chassis is divided into two equal sections for the mechanical block, power supply, and circuitry, These are completely separated by a double-layered internal chassis with copper-plating treatment to reduce magnetic distortion. In addition, the openings where the wiring material passes through the mechanical block, power supply unit, and circuitry are sealed with a special resin to prevent even the slightest air vibration from being transmitted. This is a very sophisticated structure for a chassis. The side wood panel is also adopted from this model, giving it a high-class design. As for the appearance, there are line scratches on the upper part of the front panel and the top panel, and the conspicuous part has been corrected with a stylus. There is a small chip on the lower rear corner of the side wood panel. There are no other ugly, noticeable scratches that would impair function. Since this is not a new item, there may be some other minor stains, abrasions, and loss of functionality due to the overall age of the item. [Regarding maintenance. Replaced two tray belts with new ones. The gear that drives the chucking arm and the pulley that drives the tray open/close belt, which are common to this model, were disassembled, cleaned, and completely removed from the pulleys due to grease hardening, and ceramic grease was applied to improve their proper functioning. Sewing machine oil was applied to the tray rails and linear drive unit to improve smooth movement. Replaced some electrolytic capacitors in the power supply section and audio section circuit boards with Nichicons KZ, FG, KW, and ES series, which are well known for high-end audio applications. Cleaned pickup lenses with electronic cleaner. Cleaned the RCA terminals, power plug, and other contact points with contact revival agent. Cleaned inside and outside.
