Beomaster 1600
This is a description of repairs I made to my Beomaster
1600. It is apparently very similar to the 1700, but is
FM only. Mine has aluminum front plates that make it look identical to the
1700.
I am not a stereo technician, nor a B&O specialist.
However, since there seems to be so little available online about this, I
thought I would document my experience since it may benefit someone else out
there. I recently benefitted from someone else documenting a Beogram 4002
repair. I make no promises that
this will work for you, or was the right thing to do. It is seemed to help my
unit, however.
The Problem: When
adjusting the volume with the left ribbed track belt, the track would only engage
intermittently. This made it hard to adjust the volume. It would get stuck at
one level. Sometimes it would only go up. Other times only down. Other tuning for Balance, Bass and Treble worked fine.
The Repair: I opened the unit. There are three
screws under the front face. The top hinges up and there is a stand, like a car
hood. The track drives a
belt for each of the tuning options. On observation, the track itself was slipping now and then,
but not most of the time.
The bigger problem seemed to be that the volume belt was not
turning when the tuning track turned. It was slipping for some reason.
I noticed that at the
lower end of the volume belt, there appeared to be a plastic piece that held each belt
and that this was secured by a screw with a slot in the plastic holder. I
assumed that this was to adjust the belt tension. I used this to tighten the
belt. On the first try, this seemed to make the problem worse. I then released
a little tension. This seemed to
improve the function.
Next I lubricated the Track rollers. It rotated much better then. This seemed to help too.
I then cleaned some of the dust from the
inside of the cabinet and the tracks. It is much easier to clean the tracks
with the unit open.
It is not perfect, but it is much better now. If you have a
similar problem, I hope this works for you.
