Single-Ended Triode Integrated Amplifiers
INSTRUCTIONS FOR OPERATION
PLEASE READ BEFORE PLUGGING IN THE UNIT
Welcome!
The Wright Audio Integrated Amplifiers incorporate advanced circuit characteristics and parts, which have
been chosen based on sonic quality and reliability.
Please ta e a few moments to read this manual. Doing so will enable you to thoroughly enjoy your new
amplifier's sonic quality and fully utilize its versatility. First, a few cautions. Most are common sense, but are
here as reminders. These apply to all tube and most solid-state amplifiers and are not specific only to your
Wright Audio Amplifier.
1. Never operate the amplifier unless spea ers are attached to its outputs.
2. Do not attempt to connect a subwoofer crossover / amplifier directly to the spea er terminals.
Do not attach the main spea ers to a subwoofer crossover plate where it is mar ed ‘Spea er Terminals’.
3. Never switch or disconnect input cables while the amplifier is on AND the volume turned up.
Doing so may damage your spea ers.
4. Any modifications to the amplifier's circuitry or operation with other than Wright Audio recommended
tube types voids the warranty.
5. Tubes must be replaced at the end of their useful listening life, which is about 2000 hours, or
approximately every 2 to 3 years of 'average' use. Operation past this point increases the ris of
complete tube and possible amplifier failure. See our website for suitable replacement tubes.
6. The tubes get hot in normal operation. Touching one can result in a minor burn.
7. Do not attempt to change or remove a tube while the amplifier is on.
8. This amplifier utilizes a vacuum tube rectifier, the GZ34 / 5AR4. Whenever the amplifier has been turned
off, wait at least 5 minutes before turning the amplifier on again to allow it to cool. Not doing so stresses
the tube.
9. Always install tubes of the identical numbers as shown on the enclosed sheet, on the amplifier's top
surface or on the stic er on the amplifier's bottom plate. Inserting ANY other tube number will cause
unsatisfactory operation and may damage the amplifier and tube. Tube numbers are always shown on
the tube and tube box.
10. Do not open the bottom cover of the amplifier. Lethal voltages exist within, even when the power cord is
disconnected from the soc et. It should be returned to Wright Audio if there is a malfunction.
11. Connect the unit to an electrical outlet providing 50 to 60 cycles AC and the voltage as mar ed.

INSTALLATION
1. Position the amplifier so that children or pets can not inadvertently touch the tubes.
2. Locate the amplifier where there is adequate ventilation – at least 5 inches of space above it.
3. To minimize the chance of hum, place it away from other units’ power transformers and motors.
4. Be sure the amplifier’s power switch is in the ‘Off ‘ position and insert the tubes as mar ed by
numbers on the tubes. Ta e care to align the ‘ ey’ at the base of each tube with the soc et ‘ ey’. With
the miniature tubes, a gap exists in the pins which indicates the correct alignment. Be sure to press the
tubes gently, but firmly all the way down into the tube soc ets. For the larger tubes, grasp them
at the base, not the glass portion.
CAUTION: Do not 'rock' the large octal ase tu es ack and forth to insert them in the sockets.
Doing so may reak the tu es' center post key. Likewise, do not rock the tu es when removing
them.
Due to manufacturing tolerances on oth the tu e and the socket, it may e possi le to
incorrectly rotate and insert the tu e in the socket. Check VISUALLY to e sure the ridge key on
the tu e post aligns with the cutout ridge on the tu e socket efore inserting.
5. Insert the appropriate RCA plugs to the amplifier inputs. Ma e sure the plugs are fully inserted into
the jac s with the outer s irt of the plug tight around the soc et.
6. When connecting the spea ers, be sure to observe the POLARITY of the connection. Be sure to do
the same connection for both spea ers.
LINE INPUTS
The 6 source inputs are all electrically identical, are interchangeable and compatible with all standard
analog line-level inputs.
A record turntable will require a separate preamplifier such as the Wright Audio Phono Stage.
MODEL SE610 ONLY:
For use with a stereo pair of separate self-powered subwoofers, the stereo output mar ed PREAMP is
connected to the line input of the subwoofer crossover. For use with a single subwoofer unit, connect a
‘Y’ adapter at the amplifier's left and right outputs to sum the stereo channels.
FOR BOTH MODELS:
Do not connect the su woofer amplifier to the Royale’s speaker terminals as this will provide
poor ass and may cause longer term damage.
FIXED LINE OUTPUTS
The amplifier can direct any source input to any one of three outputs. These outputs are passive and do
not require that the amplifier be powered on. These can be useful for a stand-alone headphone
amplifier, a wireless transmitter, video pass through or for recording. Keep the control in the 'Off' position
when not using.

GENERAL OPERATING NOTES AND MAINTENANCE
When new, your unit will require 3 to 4 days of operation for about 2 hours per day before it begins to
sound its best. It will continue to improve during the next few wee s of operation.
The small controls beneath the Volume Control adjust the individual Left and Right Channel levels.
Normally, they are ept fully cloc wise where they are nearly out of the signal path. Reducing the
volume of one channel or the other will adjust the volume balance between the channels. Turning both
countercloc wise will adjust for overly high-output sources and / or extremely efficient spea ers or
listening in a small room close to the spea ers.
Operate your Wright Audio amplifier only when you are actively listening to it. Unli e solid-state
equipment, Wright Audio amplifiers reach their optimum listening quality only in about 10 minutes, and it
is simply a waste of power and tube life to leave the amplifier on continuously.
It is normal for the larger power transformer to become very warm after a few hours of operation.
TROUBLESHOOTING
The unit has been designed to be as free from trouble as possible. However, a couple conditions can
occur which will affect the amplifier’s operation.
TUBE ‘GLOWING’ OR FUSE FAILURE
If either of the large output tube plates (the grey, chimney-shaped structure inside the tube) glows a dull
to bright red color soon after warmup or suddenly during operation, it is probable that the tube is
defective. Tube substitution should be tried. DO NOT continue to operate the amplifier with a defective
tube, as other parts will be damaged. If tube substitution does not solve the problem, refer servicing to
Wright Audio.
The amplifier is provided with output tube cathode TEST jac s placed in close proximity of the tube being
measured and a convenient GROUND jac located behind the GZ34 / 5AR4 tube. A DC voltmeter may
be used to measure the individual tube’s cathode voltage. A reading of positive 28 to 36 volts is
considered normal for EL34, 6CA7 and KT77 tubes and the tube must be replaced if the reading falls
outside these parameters, preferably in pairs.
NOISE
Any noise or hum encountered during the life of the amplifier will normally be traced to dirty or otherwise
poor connections at the input / output jac s, a poor tube pin-to-soc et connection or a faulty tube.
The best remedy is to apply isopropyl alcohol to a cotton swab which can be used to clean the
connection. Do not use spray-type contact cleaners on the tube soc ets or around the connections at
the rear of the amplifier as this may damage the finish or parts.
Liberal application of cleaner to the tube pins which are then inserted in the tube soc ets usually cures
any noise original from this source. The application may need to be repeated for satisfactory results. Do
not insert anything into the tube soc ets except the tubes.
Noise originating from operation of the controls indicates the controls or switches are dirty or worn.
