能配B77抹音磁头吗
手里暂时无B77抹音头,不过你可先买录放头,价格减去200元.抹音头以后再配.
As a magnetic head wears in normal operation, certain conditions and minor problems develop which indicate a gradual deterioration in performance. These indications include:
[*]Slight loss of high frequency response
[*]Signal amplitude instability
[*]Overall loss of level
[*]Unstable tracking and tape path
[*]Distorted signal
[*]Excessive oxide build-up
Generally these symptoms can be attributed to an uneven change in contour due to wear, or in the case of ferrite, gap deterioration caused by material erosion. The change in performance is usually very slight; it can be normally compensated for by adjusting record or playback equalization and mechanical head alignment. As the wearing continues, however, a point is reached in which the acceptable performance can not be achieved by compensation or adjustment. Our studies show that in most cases, less that 50% of the depth of the gap has worn at this stage. As a result, proper relapping will restore an unserviceable magnetic head to its original performance specifications.

请288C开友过目,边条是从面版上撬下来的,撬坏一个塑料的,这一对是铸铝的,不容易.
翻盖拉簧只凑上2个,在国内再配2个应不难.
