Precautions
Installation place
Install this unit in a location where good ventilation and heat
radiation are assured. Especially, installation of this unit where
direct sunlight is present, where the temperature rises exces-
sively high such as close to a heater, or where it is humid
or dusty may cause a malfunction even if heat is efficiently
released. Therefore, do not install this unit in such places.
Ventilation holes
The ventilation holes on the top and bottom boards of this
product must not be blocked because this unit is a vacuum
tube amplifier and generates considerable heat. If the ampli-
fier is installed on a rack or the like, secure ample space for
cooling and leave the door open. Do not pile up other things
on the amplifier and never put articles on it. Failure to observe
this may cause a malfunction.
Note:
For heat dispersal, do not install this equipment in a confined
space such as a book case or similar unit.

Precautions in connecting with other
components
When connecting this product to input devices such as a
control amplifier, be sure to turn off the power of this prod-
uct and all other connected devices. Otherwise, a very strong
noise may be generated and destroy the speakers. In the
worst case, this can cause equipment malfunction.
The pin-plug to be inserted in each input terminal of this unit
shall be pushed in firmly. If the grounding terminal is inade-
quately connected, noises including hum may be generated,
resulting in an adverse S/N ratio.
Cautions in connecting speakers
When making speaker system connections, be sure not to
cause short-circuiting between
!
and
@
of the speaker ter-
minals and speaker input terminals of this unit. If signals are
applied to the amplifier with its circuit left short-circuited, a
large current may be carried in the output circuit and cause
malfunctioning.
The sound is not generated shortly after
the power supply is turned on.
This product is a vacuum tube amplifier, and therefore, it can-
not deliver a sound until the vacuum tube heaters warm up.
You can enjoy music 1 minute or more after turning on the
power. We therefore advise initially setting the volume control
at a low level. After that, you may move the volume control to
your favorite sound level after the initial sound comes out of
the speakers.
Repair and adjustment
When repairs and adjustments are needed, please consult
with the dealer where you bought the unit.
Cleaning
For cleaning, use a piece of soft cloth to wipe the unit such as
cleaning cloth. When the dirt is hard to remove, use a small
amount of neutral detergent to wipe, and then wipe the unit
with dry cloth. Do not use a solvent like benzine or thinner
because such a substance can damage the exterior.
