SONY CDP—497的主要指标是比较好的。能适合一般发烧友的要求。本机属于低档机,摩机余地大,摩机后音质能进一步提高。摩机时以节约发烧的原则对该机不作大改动。摩机时需注意静电处理。一、电源部分在电源滤波电容C_(203)、C_(204)、C_(211)、C_(208)、C_(209)处各并一只拆机的0.1μF和1μF的WIMA聚丙烯电容。IC203(RC4558)是数字电路电源所用运放,现将其换为LF353。
SONY CDP-497’s main indicator is better. Suitable for average enthusiasts. This machine is a low-end machine, large motor room, after the sound quality can be further improved. Motorcycles to save the principle of fever on the machine without major changes. Motorcycle should pay attention to electrostatic treatment. First, the power part of the power filter capacitor C_ (203), C_ (204), C_ (211), C_ (208), C_ (209) and a disassemble of 0.1μF and 1μF WIMA polypropylene capacitors. The IC203 (RC4558) is the op amp used for digital circuit power and is now replaced by the LF353.
