Observing the way they run will help you set tension on the belts. The belts
should not be flopping loosely. The belts between the motor and the flywheel
should be tight enough that the belts run true and the platter reaches speed in
roughly 10 seconds. Use the measurements in the diagram as a beginning.
The belts between the motor and the flywheel should be powdered when new
and every month. You can use baby powder or corn starch for this purpose.
Make sure that the belts run relatively level from motor to flywheel and from
flywheel to platter.
DETAILS ON AIR SUSPENSIONS
The TNT-5 uses pneumatic Micro-actuators in the four suspension towers.
These actuators come with very little air pressure from the factory. When you
add air, you should use a hand pump with a quick release valve. Fill them by
hand with two quick bursts of pressure.
You can lower the pressure for a lower resonant frequency and greater isolation
by unscrewing the caps and touching the needle in the center of the valve with
the tip of a Phillips screwdriver or Allen wrench. By carefully letting out air,
you can set the level of the turntable without rotating the legs.
Never lower the air pressure to less than 1/8
th
inch clearance between the
stainless steel tower and the black cone shaped foot.
Try to get the table as level as possible with the air suspension and then final
level the TNT by rotating the bottom cone shaped foot.
REMEMBER: THE HIGHER THE PRESSURE THE FASTER
THE TABLE SOUNDS, THE LOWER THE PRESSURE THE
WARMER THE TABLE SOUNDS. HIGHER PRESSURES WILL
MAINTAIN LEVEL SETTING LONGER.
