INSTALLATION & SETUP

HOW TO MOUNT AND BALANCE THE ARM
To mount the arm wand, gently place the central arm
bearing cup directly on the main pivot on the cross arm.
The tone arm now sits in position, held in place by the
mysterious power of gravity.
Balancing any tonearm is a delicate operation requiring
steady hands and a set of scales, acurate to .01 of a
gram. The “heart-shaped” counter weight on the Cobra is
fixed in distance from the arm pivot.
Under the counter weight is a hollow section where
weights of varying thickness can be removed or attached
to balance the cartridge. These weights are used to
establish the tracking force close to optimum.
Final adjustment to tracking force is accomplished by
winding the 8mm fine weight adjustment screw at the
rear of the arm. Winding in, increases tracking force,
winding out decreases the tracking force.
