The VT-4 is carefully packed for shipment and it should survive all but the
most brutal handling. If there is any damage, keep the shipping material for use
during any possible claim for damage with the shipper.

Mounting
The VT-4 is designed for installation in a standard 19 inch rack. It requires 5.25
inches of vertical space, but additional spacing between it and adjacent equipment
is recommended for adequate cooling. Ideally, a ventilated panel at least 1 rack
unit high (1.25 inches) should be installed above and below the VT-4 (and around
any other heat producing equipment for that matter). Be sure the bottom vent slots
are not blocked. It is essential that air can flow into the bottom and out of the top
of the VT-4. Equipment that runs cool can last for a very long time.
In tight equipment enclosures, be sure there is adequate air flow. Forced air
cooling will benefit all your equipment.
The VT-4 can also be used without a rack, placed on a table, counter, or even
on the floor. Optional rubber feet are available, when requested at the time of the
order.
Moderate electrical and magnetic fields in the vicinity of the VT-4 should not
cause any degradation in noise performance, due to the well-shielded construc-
tion, but proximity to devices with motors or large power transformers (i.e. tape
machines or power amps) should be avoided.
Although the vacuum tubes in the VT-4 are selected for minimum microphon-
ic response, it is a good practice to avoid mounting locations that subject the VT-
4 to very high sound or vibration levels.
