OTHER INFORMATION

OTHER INFORMATION

As cassette tape rubs
across the playback and
record heads, a brown
deposit of loose particles
may be left on the heads
and capstan wheel.
Cheap low quality tape
will do this very quickly!

A build up of deposit will reduce sound
quality and lead to tapes being "chewed up".

With the mach ine switched on and the
cassette door open, press play. This will move
the heads up and engage the capstan wheel.

Impregnate a cotton wool stick with cassette
head cleaner or a little methylated spirits.
Then gently wipe over the heads to remove
the deposits (as illustrated left).

Be careful not to trap the cotton wool stick
between the rollers when cleaning the capstan
wheel. Allow the cassette heads and capstan
head a chance to dry for a few minutes before
playing cassettes.
