No small mountain programs, tapes,

Gia our devices are playing with tapes not worse
import, but in terms of writing, they give odds
expensive centers in Japan. Therefore I
tasked to educate the people, ie
you, what cassette that of a
represent.

   For a start, a few rules Liabilities
belorussian prevent any of the above
more vehicles if they hit you with a
 hands.

  1. To avoid damage to the films:

   Replace rubber roller prolonged, which
tory right of the head. Rollers
be freely available in shops. Nor
mine is totally flat, level of
surface of the perimeter of the roller, with the ideal free
Rays radial angle between the surface
 perimeter and the sides of the roller.

  2. For the same reason and for
Good Features:

   Replace the heads. When
presence on the surface of the head even
a small depression - to be replaced. To
the entire apparatus is perfect sendast
24GM081 and above. On sale they are, are
inexpensive. To avoid repeated formation
tions basins required as accurately as possible the condition
tanovit head relative to the ribbon ve
 rtikali. The slope also affects the sound.

  3. To prevent all kinds of direct
ladok and improved features:

   Replace all electrolytic capacitors
new from the store, import, and black
celluloid obertkah.Nominaly left
are the same. Capacitors less
1mkF better be replaced by non-polar ceramic
cal yellow or orange flowers, once
course, too new and imported. Do not touch
no podstroechnikov in advance of all
these steps!

  The review involves a lifetime
tsya everyday exploitation of from 3 to
8 hours per day.


   Well, now go directly to the

   All logic is collected on the basis of CMOS and tract

   RECOMMENDATION: Replace nizkonadezhnye

   FEATURES: Approximate service life

about 8 years. Spectral range after
