PRECAUTIONS, INSTALLATION & USER INFORMATION
1. Always be sure your hands are clean and free of any dirt or oil before carrying your Ayon Vulcan.
Carry the amplifier with both hands by gripping its side. Handle the Vulcan with respect, it is heavy.
2. Never hold the face plate against your clothing as coarse materials, stitching, belts and the rivets
from denim pants can mar the surfaces. Use a soft cloth with non-abrasive cleaning product to clean
your amplifier.
3. Gloves or a soft cloth will prevent "fingerprinting" of the tubes during their installation.
Do not touch the tubes without the use of a cotton glove or soft cloth.
4. Take care of the precision toggle switch selectors on the rear when moving or transporting the
Vulcan.
5. When the unit is on, be careful not to touch the vacuum tubes. Vacuum tubes get HOT.
6. The unit should be put on an adequate ventilated place; The Vulcan gets very warm!
Allow clearance of a couple inches in all directions so as to allow air to flow. Do not place the
amplifier directly on a carpet or any surface that will block air circulation under the amplifier.
7. Avoid placing the unit indirect sunlight or near sources of damp. Never put any objects directly on
top of the unit.
8. The power cord must be earthed . Never touch power plug with wet hands. Please pull out the
AC power cord by the plug instead of dragging it. Disconnect from power before removing bottom
plate is mandatory.
9. For best performance, place the Vulcan on a solid, horizontal and non-resonant shelf where there is
no risk of being knocked or subjected to vibration such as from loudspeakers.
10. The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or
damaged by lightning. For protection of the audio system during electrical storms, remove the mains
plugs.
11. Insert the vacuum tubes in accordance with the designated tube numbers into their relative assigned
sockets. Important: Pay close attention to the direction of socket pins never force a vacuum tube
into place. Tube should glide right in. If the direction is wrong and you force the tube, damage to the
socket pins will occur.
12. Check your speaker connections! Do not operate amplifier without insuring that speakers are
connected to the amplifier. Never let run a tube amplifier into a short circuit, the output transformer
will soak up a lot of energy before failing, but if the short persists the output transformer could be
damaged.
13. Important: To switch on or off always use the power switch of the equipment, the power switch
(on/off) is located at the front left corner of the bottom plate.
14. Insure that the Ayon logo, located on the front panel of the Vulcan, illuminates .
15. The Vulcan must be protected from humidity – if the unit is moved from a cold place to a warm
room, leave the unit for 3 hours or so to allow sufficient time for the moisture to evaporate.
16. The Vulcan amplifier should not be left running when not in use. If you will not be listening to the
amplifier for more than an hour, it is advised that the amplifier be turned off. Unlike solid state
amplifiers, tube amplifiers should be shut down when not being used. This will greatly prolong tube life.
17. It is normal for vacuum tube equipment to runs very warm if used for prolonged periods.
18. Do not use a speaker with impedance lower than 3 ohms on either of the outputs.
19. Changing the tubes: Make sure that the amplifier is switched OFF and the tubes are sufficiently
cooled down.
20. Warning : Never attempt any measurement or adjustment yourself as voltages inside the tube
amplifier can be lethal. Do not work inside a tube amplifier when you are not qualified to do so.
