INSTALLATION PROCEDURE

Ventilation:

The unit is well ventilated in itself, but sufficient space must be allowed
around it to permit proper air flow. Install the amplifier in a manner to allow for
unrestricted circulation. Do not place books or other objects on the cage or in
the immediate vicinity of the instrument. Reducing the air flow will result in
sharply reduced component and tube life. Allow at least 4 inches above the unit
for cabinet installation.

straight out or slanting them slightly will depend on your room size, acoustic
effect and where you will be seated for listening. It may be necessary to experi-
ment with speaker placement until best rcsults are obtained
