ADJUSTING SPRING TENSION FOR BRISTOL MOTOR

Before adjusting the motor tension, turn on the amplifier and set the speed control to 45. Place your finger on the side of the platter and stop the platter. Listen for the motor to stop. The motor should stop within a second or two. If the motor stops immediately the tension is too tight. If the motor continues to run longer than a second or two the tension is too loose. To adjust the motor tension, remove the platter. Under the platter will be the motor tension screw. Loosen the nut on the screw. To decrease tension lower the screw head (turn the screw clockwise). To increase tension raise the screw head (turn the screw counterclockwise). Place the platter back on the turntable and recheck the tension setting. Should the motor tension screw become too high and hit the platter, remove the amplifier from the case and reduce the height of the screw while increasing the tension from inside the unit.
