VL-1000 Technical Supplement
Introduction
covered by warranty. For the major circuit
boards, each side of the board is identified by
the type of the majority of components installed
on that side. In most cases one side has only chip
components, and the other has either a mixture
of both chip and lead components (trimmers,
coils, electrolytic capacitors, packaged ICs, etc.),
or lead components only.
While we believe the technical information in
this manual is correct, Yaesu assumes no liabili-
ty for damage that may occur as a result of typo-
graphical or other errors that may be present.
Your cooperation in pointing out any inconsis-
tencies in the technical information would be
appreciated. Yaesu Musen reserves the right to
make changes in this transceiver and the align-
ment procedures, in the interest of technological
improvement, without notification of owners.
This manual provides technical information
necessary for servicing the Yaesu VL-1000 HF &
50-MHz-Band Linear Amplifier. It does not in-
clude information on installation and operation,
which are described in the VL-1000 Operating
Manual provided with the transceiver, or on ac-
cessories which are described in their manuals.
The VL-1000 is carefully designed to allow the
knowledgeable operator to make nearly all ad-
justments required for various station conditions,
modes and operator preferences simply from the
controls on the panels, without opening the case
of the Linear Amplifier. The VL-1000 Operating
Manual describes these adjustments, plus certain
internal settings.
Servicing this equipment requires expertise in
handling surface mount chip components. At-
tempts by unqualified persons to service this
equipment may result in permanent damage not
