Notes:
The
circuit
design
and
layout
has been
chosen
carefully
by
expert
audio
engineers
with
many
years of
development
and
refinement
experience
in audio
excellence.
This
achieves
the
highest
quality
of
musical
reproduction
with
maximum
dynamic
range
and
minimum
distortion
for
accurate
and
emotional
delivery
of the
sound
stage.
Direct
coupling
techniques
have
been
used on
the
Electro-Harmonix
Double-Triode
input
stages
to
improve
signal
transient
response.
Extra
wide
bandwidth
audio
output
transformers
couple
the
Electro-Harmonix
EL34
Class
A/B
pentode
output
valves
to the
speakers.
Output
valves
are all
bias
matched.
 Each
EL34
valve
has been
tested,
matched
in
pairs,
then
custom
installed
into the
A3500-SS.
Internal
bias
adjustments
have
been
factory
made
specifically
to suit.
The
A3500-SS
valves
are then
removed
and
individually
packaged
for
transportation.
Therefore
each
EL34
Valve is
labelled
with the
appropriate
socket
number
to aid
installation.
Hand
selected
high
quality
electrolytic
and
non-electrolytic
capacitors
are used
in both
the
power
supply
and in
critical
signal
areas to
improve
the
midrange
definition
and top
end
transients
with the
added
benefit
of
long-term
reliability
and
tolerances.
Extra
attention
to
internal
wiring
positioning,
use of
OFC
cabling,
gold-plated
relay
selectors,
among
other
details,
all
combine
to
enrich
the
listening
experience.
 
The
A3500-SS
is
beautifully
finished
in 7mm
thick
premium
quality
brushed
aluminium.
 The
stainless
steel
panels
between
the
mains
power
transformer
and
output
valves
reduce
the
transformers'
running
temperature
and
shield
the
output
valves
improving
over all
amplifier
efficiency.
Gold
plating
is used
where
possible
for
long-term
reliable
connections.
This
includes
all
valve
sockets,
audio
connections
and
audio
switch
contacts.
We
recommend
the use
of high
quality
interconnects
and
speaker
cables
to
enable
the
A3500-SS
to
reproduce
uncompromised
sound
quality
from
your
audio
equipment
and
speakers.
The
excellent
blend of
components
and
circuit
design
topologies
used in
this
amplifier
offer
long-term
reliability
and also
enable
very
tight
fast
clean
low bass
performance
normally
not
found in
valve
amplifiers
with a
warmth
rarely
achieved
by solid
state.
Enjoy a
new
dimension
in
sound.
