盒式录放机早已进入千家万户,由于价格低廉、效果良好而深受用户喜爱。用过一段时间后笔者发现,一般高档盒式录放机机械部件故障占70～80%,电子线路故障为30～20%;对于普及型低档盒式录放机,因设计上欠精细、制造粗糙,调整和装配不完善,机械故障占50～40%,电子线路故障占50～60%。机械故障中最常见、多发的故障就是绞带。下面介绍绞带的现象与排除方法,供参考。绞带是在放音中,磁带溢出盒带,缠绕在主导轴或压带轮上,产生绞带的原因有:1.磁带的质量不好,只能更换;2.磁带在盒带内松垮,处
Cassette player has entered millions of households, due to low prices, good results and loved by users. After a period of time I found that the general high-grade cassette recorders mechanical parts failure accounted for 70 to 80%, electronic circuit failure of 30 to 20%; for universal low-grade cassette players, due to the design due to fine, rough manufacturing, Adjustment and assembly imperfect, mechanical failure accounted for 50 to 40%, electronic circuit failure accounted for 50 to 60%. The most common mechanical failure, multiple faults is the ribbon. Here’s the phenomenon of ribbons and exclusion method for reference. Ribbon is in the playback, the tape overflow tape, wrapped around the capstan or pressure pulley, resulting in ribbons are: 1. The quality of the tape is not good, can only be replaced; 2. The tape in the cassette loose, Department
