2-5-2. BACK TENSION
1.
2.
Hold the right tension arm up using a rubber band.
Mount an empty 7” reel onto the supply (left) reel table, and at-
tach a spring scale to the reel with a string.
. Place the deck in the play mode.
. Using a steady, smooth motion, pull against the motor torque to
draw the scale away from the reel.
. After making sure that the reel motion is smooth (the string
should not be rubbing against the reel flanges), note the value in-
dicated on the scale.
. The proper value is between 220 g-cm (3.06 02-inch) and 280
g-cm (3.69 oz-inch).
. If necessary, adjust the slider of the resistor (R802) until the
proper torque value is obtained. See Fig. 2-6.
