Specifications
antee
period,
DYNACO
will replace
any
non-stand-
ard
parts
at
net
prices.
Many
of
the
components
are
standard
items which
can
be purchased from most
electronic
supply
stores.
If
transformers
are
returned
for factory
repair
or
replacement, they
should
be removed from the equip-
ment
without
cutting
leads short.
If
leads
are
cut
rather
than
unsoldered so
that
they
are
unusable,
the
transformer
guarantee
is void.
In
the
event
the
assembled
kit
does
not
function
properly or breaks
down
after
use,
DYNACO
will
service
the
kit
for a fee of $5.00 plus
the
cost
of
parts
which
have
been
damaged
or
are
past
guarantee.
This
service facility is
not
available for
kits
which
are
in-
completely wired
or
which have been wired with
other
than
rosin core solder,
or
in
which changes have been
made
without
factory authorization.
In
addition,
NO
PARTS
WILL
BE
REPLACED
NOR
WILL
ANY
SERVICE
BE
RENDERED
FOR
KITS
WHERE
THE
GUARANTEE
POST
CARD
HAS
NOT
BEEN
RETURNED.
THE
SERIAL
NUMBER
ON
THIS
INSTRUCTION
BOOK
MUST
BE
MENTIONED
IN
CORRESPONDENCE,
PARTS
RETURN,
OR
KITS
RETURNED
FOR
FACTO-
RY
SERVICE.
It
is the factory prerogative to
limit
the
service facility to
one
year
from
date
of purchase.
When
shipping
a
unit
for service, a
note
must
be
attached
specifying symptoms,
the
name
and
address
of the sender,
and
the
serial
number
of
the
unit.
The
amplifier should be securely packed with stuffing in-
side
the
cover to
prevent
the tubes from coming
out
of
their
sockets
in
shipment.
It
should
be placed
in
a
rugged
carton
and
surrounded
with
plenty
of shock
absorbing packing material.
The
original
carton
is
not
suitable
for
shipping
an
assembled amplifier.
Shipping
should
be by
Railway
Express, prepaid;
repaired kits will be
returned
by
Railway
Express
collect for
shipping
and
service charges unless these
are
prepaid. Parcel post is
not
a safe method of ship-
ment
for assembled units.
Dyna
Co. assumes no responsibility
or
liability for
damages
or
injuries
sustained
in
assembly
or
opera-
tion
of
the
DYNAKIT.
