End of the Bose End Levels

Hello community,

I have bad news :-((((
As already described in several postings, I've been in the last few years
deals with the power amplifiers of the Bose sound system. The same way that the
Numerous measurements depicts the IC ́s dying over time. Because these ICs
but by Bose and thus are not available in free trade one can
I guess I forgot to repair the power stages unless someone finds out,
which IC ́s are really hiding behind the Bose label. It's probably,
that these ICs are simply relabelled.

The problem with the power stages is that some elcos on the board with
drying out of old age and starting to become low-impaired.
The ICs on the board seem to suffer along with this. The way it
They will eventually die of heat death. This effect
is not necessarily noticeable in the fact that the power stages do not
play more, but rather slowly take off. Reinforcement of the power stages
slows down and a flutter noise slowly becomes audible. The Flatter Noise
is due to the defective elkos. If one replaces the Elkos of the final stage,
Then the flutter noise disappears. However, what remains is the decline in the
Reinforcement of the final stages probably due to the deceased IC ́s (partial death).

Surely, one of you knows someone who knows someone who
someone at Bose knows who tells you which ICs really in the

Give the final stage.
