INTRODUCTION

Congratulations on your purchase of the Audio Note (UK) VINDICATOR Silver
Signature stereo power amplifier.
It is a Pure Class A Singled Ended valve amplifier that uses the highly regarded 2A3
triode valve, producing a level of performance that is radically superior to the vast
majority of current designs.
It has been specifically engineered for sonic performance rather than technical
specification, and fulfills all Audio Note (UK) Level 3 criteria: -
Pure Class A operation
Zero Negative Feedback
Single Ended Output Stage
Valve Rectification
Directly Heated Triode operation
The Silver Signature version builds upon the already superb performance of the
standard VINDICATOR, and features the following additions: -
Audio Note (UK) Copper Foil signal capacitors
Cerafine capacitors in critical areas
Audio Note (UK) 2 Watt Tantalum film resistors
Audio Note (UK) SHiB Double C-core output transformers
Please take care when unpacking your VINDICATOR Silver Signature stereo power
amplifier. Choose a clean, clear location to unpack your unit. Be aware that the
amplifier is very heavy; before attempting to unpack or lift the unit, check the weight
and if necessary use more than one person so that it can be moved safely and
easily.
We recommend that you retain and carefully store all of the original packing
materials, in case transportation / shipping is required at a later date.
Select a suitable location for the unit. This should be a dry, dust free and level area,
preferably shielded from direct sunlight and free from vibration. Also ensure that the
location is stable and capable of carrying the weight of the unit.
A suitable mains power outlet must be close to the location; power cords must not be
pulled or stretched tightly in an attempt to reach a wall socket. If the power cord will
not easily reach the socket, choose a closer location!
Please ensure that adequate ventilation for the unit is provided, and that airflow
through any ventilation slots in the unit is not restricted. We recommend a distance of
at least 20cm free space is maintained above the unit, and preferably it should be
sited in free space or on the top shelf of your equipment rack or table. Please also
remember that valve equipment operates at extremely high temperatures, so a
position that is inaccessible to any children or animals is essential.
VINDICATOR SILVER SIGNATURE POWER AMPLIFIER
UNPACKING AND INSTALLATION

The amplifier is shipped without its valve compliment installed. It is necessary to
install the valves before operation.
It is essential that the valves are installed correctly or serious damage that is not
covered by the warranty will result. We recommend that your dealer perform
this procedure for you if you are in any way unsure.
FIRSTLY, ENSURE THAT THE AMPLIFIER IS NOT CONNECTED TO A MAINS
ELECTRICAL SUPPLY, AND THAT THE POWER CORD IS NOT CONNECTED TO
THE AMPLIFIER.
Now remove the valves that are packed inside the amplifier and carefully unwrap
them. Also inspect the amplifier to check that nothing has become damaged or
dislodged during transit.
2 x 2A3 output valves
1 x 6SL7GT input stage valve
1 x 5R4GY rectifier valve
Once again, please understand that it is absolutely vital these valves are fitted
correctly.
Looking from the front of the amplifier install the 2A3 valves first. Inspect a 2A3 valve
base and you will notice that two of the pins are larger than the other two; this is to
help ensure that the valve can only be inserted one way.
Now examine the two large apertures located in the top plate of the amplifier,
between the single front valve base aperture and the large, black, square transformer
cover; you will notice that two of the four holes in each aperture are larger than the
others. Line up the large pins on the base of the 2A3 valves and the large holes in
each valve base, and with gentle but firm pressure insert the valve into its socket.
Next, examine the single 6SL7GT input stage valve. You will see that there is a rib on
the central pin of the valve, which ensures that it can only be inserted into the valve
base correctly. Locate this rib and align with the corresponding aperture in the centre
of the valve base, located in the top plate at the front / centre of the amplifier. With
gentle but firm pressure,insert the valve.
Next, examine the remaining 5R4GY rectifier valve. You will see that there is a rib on
the central pin of the valve, which ensures that it can only be inserted into the valve
base correctly. Locate this rib and align with the corresponding aperture in the centre
of the valve base, located in the top plate towards the rear of the amplifier, between
the two large, black, square transformer covers. With gentle but firm pressure,insert
the valve.
Check one more time that all of the 4 valves are correctly fitted!
VALVE INSTALLATION

Line inputs Being a stereo power amplifier, the VINDICATOR Silver Signature is
fitted with one pair of single ended / RCA inputs. Looking from behind
the amplifier, they are located at the right hand side of the rear panel.
The Black socket (top) is for the Left channel, the Red socket (bottom)
is for the Right channel. Connect the output from your preamplifier to
these inputs.
Speakers Each channel is equipped with 3 colour coded binding posts for
connection to your speakers, located on the rear panel.
Looking from the rear of the amplifier, the 3 binding posts at the top
are for the left channel and the 3 binding posts at the bottom are for
the right channel.
Connect the amplifiers black speaker output binding post marked as
“0” to the black / negative terminal (also marked “ –“) on the speaker.
Connect the amplifiers red speaker output binding post marked “8
Ohm” to the red / positive terminal (also marked “ + “) on the speaker.
The other red speaker output binding post is marked “4 Ohm” and
may be used with 4 Ohm speakers. If you are uncertain whether your
speaker system is specified as 4 or 8 Ohm, try the following test once
all other connections are made and the amplifier is operational.
Compare the sound quality using a familiar recording with the
speakers connected to the 8 ohm connections and then the 4 Ohm
connections respectively. The selection that produces the best
frequency balance and maximum dynamics should be used.
Mains The VINDICATOR Silver Signature uses an IEC 320 mains inlet
socket. Use the supplied mains cable to connect the unit to the local
mains supply. The mains fuse and a spare are located in the inlet
socket fuse drawer.
Special Note –Make sure that all connectionsare tight and clean. For
best results use good quality audio interconnects. Although it is
perfectly acceptable to use cables manufactured by other companies,
for best results and performance, we recommend our own Audio Note
(UK) range of interconnects and loudspeaker cables. For further
information, please consult your nearest Audio Note (UK) dealer, or
alternatively please feel free to contact us directly.
CONNECTION

Once all the connections are completed and checked, ensure that the volume control
of your preamplifier / source is at the minimum setting.
Turn on all components in the signal chain BEFORE the VINDICATOR Silver
Signature; it should always be the LAST component to be switched ON, and the
FIRST to be switched OFF.
Turn on the amplifier by using the rocker switch located on the rear top right of the
back panel, just above mains inlet socket.
Bedding in The new amplifier requires about 200 hours of initial use (called
“bedding in”) before the circuitry becomes stable and optimum
performance is realized.
As the amplifier “beds in” the sound will become increasingly
smoother, detailed and open.
Once the amplifier has “bedded in” a warm up time of
approximately 30 to 45 minutes is required each time the
amplifier is switched on before optimum sonic performance is
reached.
Cleaning No special maintenance is required for the amplifier. Use a
soft, clean lint free cloth to remove any surface marks from the
casework. For finger marks / grease, use a soft, clean lint free
cloth, lightly moistened with a solution of warm water and mild
detergent. Do not use any alcohol or solvent based cleaning
products, as they may damage the finish of the amplifier.
ENSURE THAT THE AMPLIFIER IS SWITCHED OFF AND
DISCONNECTED FROM THE MAINS ELECTRICITY
SUPPLY BEFORE UNDERTAKING ANY CLEANING.
Valve Life The valves supplied with your amplifier should provide
approximately 6000 hours of operation. They are specially
selected by us, and should only be replaced with matched
pairs. Please consult your Audio Note (UK) dealer should your
valves need replacing.
