Heathkit W-5M User Manual

SPECIFICATIONS
NOTE:
There
is, as
yet,
no
general
agreement
for
specifying
amplifier
performance.
A
cursory
review
of
specifications
may
easily give a
highly
distorted
picture
of the
characteristics of
the
amplifier.
In
general,
it
may be
assumed
that
the
most
important
specifications
are those
which
are
not
shown.
At
first
glance,
the
specifications
presented here
may seem
quite
complex
and possibly,
con-
fusing.
We
feel
that it is necessary to
provide
you with
complete
and factual
information
about
the
Heathkit
W-5M
Amplifier.
We
urge
your direct
comparison of
these
figures
against those
for
competitive
amplifiers.
It is
our intention
to
furnish you
with enough
information to
point up the
fact
that,
in
general,
only
the most
optimistic
technical
information
reaches the
prospective
buyer
of
high
fidelity amplifiers.
The
specifications
below
have
been
taken
with the most
modern and
accurate test
equipment
available
today.
They are
actual
measurements
taken
on
a
typical
amplifier, under
carefully
controlled
conditions; not
to
present
the
most
favorable advertising
information, but
in
strict
accordance
with all
generally
accepted
standard
conditions.
These
conditions
are listed at
the
end
of
this
specification.
Minor
variations
from these
specifications may be
encountered
in
kit-assembled
amplifiers
.
Such
factors as
exact
lead
placement, component
variations and
tube
characteristics
are
possible
sources
of
deviations. In a
highly
stabilized
amplifier, such
as the W-5M,
these variables
may
be
disregarded
from
a
performance
point of view.

Please
note
that

curves,
portions of the characteristic
have
been
bro-
ken.
Power
measurements
cannot
be
considered valid
in this
region because they were made
with meters
calibrated to
RMS
values.
Waveform distortion
in the
broken areas
was
sufficient
to
invalidate
such
readings.
On
the power
curves,
asterisks
have
been
used
to
designate
overload
points
at
both low
and
high
frequency
limits.
