The MR-55 may be mounted in its own cabinet or shelf mounted in a custom cabinet. The tuner has been
designed to mount on a shelf rather than hang from the cast tuner panel. Rubber shock mounting feet have
been provided to offer the optimum in mechanical isolation from extraneous vibrations.
Enclosed in the instruction manual envelope are two copies of the "TUNER PANEL CUTOUT TEM-
PLATE" and two copies of the "SHELF MOUNTING TEMPLATE" for mounting the MR-55. Prepare the
cabinet for the mounting of the MR-55 by first cutting the wooden cabinet panel to receive the cast tuner
panel.
1. On the back of the wooden cabinet panel make a vertical center line on the exact center of the area
in which the tuner will mount. Extend this center line to the shelf.
2. Fold the "TUNER PANEL CUTOUT TEMPLATE" on the "FOLD LINE." The "FOLD LINE" is
the line of the top of the shelf on which the tuner will mount.
3. Place the "TUNER PANEL CUTOUT TEMPLATE" in the proper location on the inside of the cabi-
net with the fold line against the shelf. The template center line should match the center line scribed on
the panel in step 1.
4. In the center of the "Cutout Area" on the "Tuner Cutout Template" arc two holes marked "LOCA-
TION HOLES." Carefully and accurately drill these two holes with a 5/32 inch drill.
5. Transfer the "TUNER PANEL CUTOUT TEMPLATE" to the front of the wooden cabinet panel.
Match the "LOCATION HOLES" for the proper positioning of the template. Proceed with marking the lo-
cation of the six holes and the outline of the cutout on the front of the wooden cabinet panel.
IMPORTANT: DRILL THE FOUR 3/16 INCH AND THE TWO 5/32 INCH HOLES BEFORE
CUTTING OUT THE TUNER PANEL HOLE.
The cast tuner panel has a 1/4 inch overlap to cover the edges of the cutout in cabinet panel.
Next prepare the shelf for mounting the tuner.
1. Measure the thickness of the wooden cabinet panel.
2. "FOLD LINES" have been supplied on the "SHELF CUTOUT TEMPLATE" for standard pane!
thickness up to one inch. Fold on correct fold line for your wooden panel thickness.
4. Place the folded edge of the template against the back of the front panel. The template center line
must match the center line extended to the shelf in step #1 of the front panel cutout instructions.
5. Carefully mark the locations of the four 1/4 inch holes and the 8 by 10 1/4 inches, ventillation hole.
6. Drill and cut out the shelf.
Next prepare the MR-55 for mounting in the cabinet by removing the pressed wood shipping pallet from
the bottom of the tuner.
Remove the knobs by gently pulling them toward you. Remove the felt washers.
The cast tuner panel has been attached to the tuner by two angle brackets that are for shipping pur-
poses only. These are removed by unscrewing the four screws (two on each side) that hold the angle brackets
to the tuner chassis. After removing these four screws the tuner panel can be slipped off over the knob shafts.
After removing the tuner panel lay it face down on a protected surface for the following operations.
Remove the four 6/32 screws (one on each corner) that hold the two shipping brackets to the tuner panel
