Remember to always retighten those two setscrews when listening. If they are left
loose the sound will be unfocused.
H. VISCOUS DAMPING
The JMW-Classic has the ability to use damping fluid around the pivot. Use this option
sparingly and only if needed with certain cartridge like Grado or Clearaudio or if the
sound is not smooth enough.
You can now add damping fluid. Use only enough to stabilize the arm, too much will
kill the sound and make the cartridge sound slow. Try listening with and without
damping and decide which you like better in your system and with your cartridge. Fill
only ½ to begin, excess will spill over and make a mess.
I. CONNECTING TO THE PREAMPLIFIER/AMPLIFIER
ONLY USE INTERCONNECTS THAT ARE SHIELDED AND PROPERLY GROUNDED. NON-SHIELDED
INTERCONNECTS CAN HUM AND PICK UP RF.
The ground connection is available to eliminate hum if necessary. If hum is present,
first connect a ground lead from the connector block to the preamplifier or amplifier to
which the output cable is connected. If this does not eliminate the hum, run a ground
wire from the turntable chassis to the connector block as well. The block's connector
will accept bare wires, spade lugs, or ring tongue connectors.
J. PLAYING RECORDS
Before playing a record, make sure that the two setscrews in the arm base are tight.
You can use either the paper, gray urethane, or no mat at all on your Classic 1. They
sound different and one may work better in your system than the other. We prefer no
mat at all or the paper mat.
Place the rubber washer on the platter spindle, then the record on the platter, then
screw the clamp onto the spindle. The clamp will lock the rim of the record down first
forcing the air out and acting like a vacuum.
Press the power button and sit down and enjoy listening to your records!
K. GENERAL USE
Allow at least 20 hours of break-in time.
The motor will make some low-level noise. This will not get into the system. The motor
and bearings will become quieter as you use your Classic 1.
After at least one year of use, the platter bearing will need to be lubricated. Use 1/4
teaspoon of white lithium grease placed on the ball.
