2. Connection and Installation
• To prevent fire or shock hazard, do not expose this unit to rain or moisture.
• Dangerous voltages inside. Do not open the amplifier cabinets. There are no user
serviceable parts inside. Repairs should be carried out by qualified service
personnel only.
• Take care to handle the power cord carefully and not to crimp or damage it as this
can cause electric shock or damage the device.
• Do not insert any objects into the amplifier.
• To install the device, select an open place with good ventilation. The amplifier
should be placed so that the valves (vacuum tubes) are always vertical.
• The amplifier operates with alternating current voltage 240 VOLT, 50 HZ. Before
connecting power check that the required supply voltage corresponds to your local
AC supply. If a different voltage is stated, do not connect the amplifier to the mains
power, and seek advice from your dealer / distributor.
• Never pull the power cable from the cord.
• Connect to the mains power using a high quality mains cable.
• Always disconnect the amplifier from the mains power before connecting or
disconnecting any of the input or loudspeaker cables.
• Never expose the device directly to the sun or attempt to operate it outdoors.
• Do not place the amplifier near radiators or other sources of heat and generally
avoid placing the device in an adverse environment.
• All valve amplifiers need time to reach their optimal operating temperature. We
recommend, therefore, that you allow at least fifteen minutes for the amplifiers to
‘warm up’ before use. Warming up should be done with the volume control (on the
pre amplifier) set to zero, with no signal passing to the power amplifier.

3. Special Notice
Do not place the amplifier near each other while in operation because the
magnetic field emitted from the power supply can cause noise and adversely
affect audio playback quality.
Never change the position of the amplifiers during operation and wait for 20
minutes after powering off before moving, because of the high voltages that
remain in the amplifier.
Do not touch the valves during operation – serious risk of being burned!
The lifetime of the tube is 7,000 hours for Aeolos and after this time replacement
is necessary.
After use, always allow the amplifiers to cool down before re-starting (2 minutes
should suffice).
Do not operate the amplifier without a load (speaker cables attached) as this can
cause damage to the amplifiers.
