Follow the instructions below to reduce risk of electrical
hazard or injury.
Read and follow the Safety Instructions below.
Save all packing materials. The Classic 1 should only be moved or
shipped in its original packaging to reduce the risk of damage in transit.
The Classic 1 must be placed on a flat, level surface. This will make
setup easy, provide better sound quality, and put less strain on the main
bearing.
Safety Instructions
1. To avoid electrical shock, do not open the motor cover.
2. If the power cord provided with the Classic 1 does not reach an outlet,
use a heavy-duty, grounded extension cord.
3. To avoid electrical shock, always plug the Classic 1 into a grounded
outlet.
4. Do not expose the Classic 1 to rain or excessive moisture.
5. Do not touch the male pivot point of the tonearm assembly. It is
extremely sharp.

Unpacking the Box
Complete and return the warranty card. The warranty does
not take effect until the warranty card is returned.
The turntable and tonearm are packed very carefully to avoid damage during shipping. It
is important that you save the packing materials and boxes to use for shipping or moving
the Classic 1.
Set aside the bag containing the drive belt.
Remove and set aside the following items:
Alignment Jig.
Record clamp.
Power cord.
Bag containing screwdrivers and screws for mounting the cartridge.
Shure Stylus Force Gauge
JMW-Classic tonearm wand
Remove the large foam top packaging piece and place it on the side.
Make room for the turntable, it will be ready to place in its final destination
immediately.
Grab the turntable on the sides where the foam is cut out and lift straight up. Be
careful, the turntable is very heavy (40 pounds) if you need help, get it. Place the
turntable on a flat sturdy surface that will support the weight.
Lift the aluminum turntable platter from the smaller box, remove the plastic bag, and
peel off the tape covering the bearing hole. Be very careful not to hit or damage the
motor pulley when sliding the platter on to the spindle shaft. It measured +/- .0005”
when it was tested at the factory. Try not to disturb it at all. The platter can be
damaged if it is hit, be careful.
The paper protection on the platter can be used as a mat if you are not comfortable
with the record sitting on the bare aluminum platter. There is also a urethane mat
provided for those that must use a mat. We recommend bare platter listening but it is
an owner’s choice to decide.
Setting up the Classic
The Classic 1 must be placed on a flat, level surface. This will make setup easy, provide
better sound quality, and put less strain on the main bearing.
Place the turntable chassis on the shelf or stand where it will be used. The Classic 1
has very good isolation so it simply requires a good solid shelf on a rack that doesn’t
sway in the breeze. You can get very good sound by placing the Classic 1 on a maple
butcher block board about 2” thick.
2
The platter bearing is lubricated; no additional lubrication is needed for at least one
year.
Place the drive belt around the platter and around the pulley on the motor. The belt
does not have to be level on the platter. It will self-level when the platter starts
rotating. You can powder the belt with baby powder or talc for even better sound.
For 33 RPM operation, place the belt on the upper part of the pulley. For 45 RPM
operation, place the belt on the lower, wider part of the pulley. The center groove in
each diameter is usually the correct speed.
Connect the supplied power cord to the Classic 1 in the fused rear socket.
Verify the turntable is level by using a 9- or 12-inch bubble level front-to-back and
side-to-side on the platter. If it is not level, rotate the TNT mini feet up or down. If you
must turn the Classic feet more than three full turns, level the shelf or platform the
table sits on first.
The power button is on the left side, it is recessed for protection. Turn on the Classic 1
by pushing the power button and allowing 3 seconds for the platter to get up to speed.
If you bought the Classic 1 with a Dynavector 20X Special or a VPI/Grado it was
installed at the factory and you simply have to drop the arm on the bearing assembly.
BEFORE YOU BEGIN
Be very careful when handling the tone arm. The internal arm wire is exposed at the
headshell and at the rear of the arm. The wire is very delicate and physical damage to
the wire is not covered by the warranty after the arm is removed from its box.
When you remove the black tube covering the unipivot male bearing assembly be very
careful it is sharp, do not touch it, you will get punctured or cut.
There are a number of setscrews on the JMW Memorial Tone Arm. The Allen wrenches
that come with your arm will only fit the setscrews that you will need to adjust. All
other screws are factory set and should not be adjusted, except by our trained
technicians. Resetting any of the factory settings is not covered by the warranty.
