INSTALLING AC-201 TRANSFORMER HUM SHIELD

Remove the cover from the unit, lift out the platter and set it aside. Turn the unit upside down onto a pillow, foam or other material, be sure it is thick enough to support the amplifier and protect the tone arm. Remove the four screws near each of the spring feet. AT THIS POINT THE CHASSIS IS FREE FROM THE CASE AND EXTREME CARE SHOULD BE USED TO PREVENT DROPPING EITHER THE CASE OR CHASSIS. Holding the chassis and the case together, carefully turn the entire unit over to its upright position. The chassis can now be lifted out of its case, lifting the front first so as to clear the jacks on the rear panel.

Locate the power transformer mounted at the rear of the chassis. Remove the nuts from the two screws holding the top of the transformer laminates together. Place an "L" bracket over both screws pointing away from the center (see photo) and replace the nuts and tighten. Insure that the side with the threaded holes is level with the bottom of the set.

Re-route the Yellow and Red wires straight back to the back of the set, under the transformer windings if possible, to ensure clearance around the shield.

Place shield over the transformer, as shown in second photo, check that the wires are not pinched and secure with the two 6-32 x 1/4"screws.

Re assemble by placing the bottom of the case over the set, it may be necessary to press in on the front center of the chassis. Put the front two screws in the bottom first. If necessary to line up the back two screws turn the set so it is upright on the back panel where the power cord connects.
