OVERVIEW
Philosophy
In the past few years, the
engineering
has
changed considerably. At many stations, the engineering staff
has
been reduced
in
size and new responsibilities have been added. At
the same time, equipment has gotten more complicated and
specialized. Thus, many practitioners of the broadcast electronic
arts are forced to become
systems
engineers, emphasizing
equipment application rather than component-level trouble-
shooting.
This is
probably a positive development since it really would be
impossible for a station engineer to fully understand the internal
nuances of all the wonderful new high-tech stuff that
is
now
available to improve station operations! Also, as equipment
becomes more sophisticated and specialized,
spare parts
for every eventuality has become difficult.
Thus, we don't really expect that much component-level
troubleshooting will occur.
So,
to support you when you need help,
we keep spare boards available for fast
shipping.
In
most
cases,
we will swap boards with you at no cost. In the five
years since we introduced the Telos
10,
we have yet to charge for a
routine repair.
However, despite the comments above, we do provide full
schematics and component level troubleshooting information in
case you have the need or desire to tackle a repair (or
modification) yourself.
Another reason we provide the
information
is
to satisfy your curiosity.
If you are like me, you
probably just
have
to know what's happenin' inside the
f a n c y
box.
So
we tell you.
