air out of both jacks to lower the platter
onto the bearing spindle. As the platter
is being lowered rotate the platter as
required to align the platter mounting
holes with the holes in the spindle. A
small screwdriver may inserted into the
mounting holes to rotate the spindle for
final alignment.
8.
Install but do not tighten the 8, 10-32
screws used to fix the platter to the
bearing spindle.
9.
Once the platter is in place wait for the
spindle displace the oil and fully seat.
This will take roughly 30 minutes so be
patient. When fully seated the gap
between the platter and the base will
be about 0.10” (slightly less than 1/8
th
inch). WARNING, do not spin the
platter until the bearing has fully
seated!
10.Once the platter has seated use the
provided dial indicator to accurately
center the platter onto the spindle as
follows:
loosen all 8 of the platter mounting
screws and then lightly tighten two
screws on opposite sides.
Wrap the end of the dial indicator
rod with scotch tape to avoid
scratching the edge of the platter.
Setup the dial indicator and stand
so that the rod of the dial indicator
presses against the edge of the
metal platter plate. The dial
indicator shaft should point
straight out from the edge of the
platter.
Place the dial indicator so that the
dial is deflected at least one half of
a rotation.
Slowly rotate the platter and locate
the point where there is maximum
deflection of the needle. Also note
the amount of deflection.
Use the provided rubber mallet to
tap on the edge of platter (at the
point of maximum deflection) to
move the platter ½ of the amount
of deflection noted before. You may
need to hold the dial indicator base
in place to keep it from being
jarred during this operation. A
series of small taps works best.
Repeat this process until there is
less than 0.002 (two tick marks) of
deflection as the platter is rotated.
This is a tricky process and may
take some time to master. Please be
patient.
Once the platter is centered tighten
two of the bolts and then recheck.
Sometimes tightening the bolts will
change the centering slightly. If
this happens loosen the bolts just
enough that the platter can be
adjusted and repeat the centering
process.
Tighten the remaining 6 bolts.
11.
Thread the chrome record centering
pin into the top of the platter. Tighten
the centering pin with pliers will keep it
from backing out while using the
clamp.
12.Connect the cable from the base to the
motor controller.
II. Armboard Setup
The model 460 armboard is secured by a
3/8” bolt extending from the armboard to
the bottom of the 460 base. A 3/16” allen
wrench and a ratchet with a 11/16” socket
are required to adjust and tighten the
armboard.
1. Start by using the 3/16” allen wrench
to set the armboard tension so that the
armboard is steady but loose enough
that it can be adjusted by hand. The
allen wrench is inserted into the center
of the armboard bolt from underneath
the turntable base.
2. Install the tonearm and cartridge and
adjust the overhang by rotating the
armboard.
After the overhang adjustment is
complete tighten the armboard bolt. Start
by using the 3/16” allen wrench to tighten
the armboard bolt. The proper amount of
torque is roughly what can reasonably be
exerted using a small allen wrench. Next
tighten the armboard bolt locking nut
using a ratchet and a 11/16” socket. Only
use light pressure when tightening the
armboard nut.
