Head demagnetization
In order to maintain good sound quality, it is recommended that the
head assembly be demagnetized
when
distortion or poor sound
quality persists after cleaning the head. If the head assembly be-
comes magnetized, it could create loss of high end frequency re-
sponse.
Several types of head demagnetizers
are available and may be
purchased separately at local electronics supply stores. Follow the
instructions that are supplied with the device.
Do not bring any type of metal objects or tools, such as magnetic
screwdrivers, in contact with the head assembly.
