Prepping The Cabinet - StewMac ’57 MINI TWEED Assembly Instructions Manual

Start by prepping the cabinet
Prepare the cabinet for mounting the
amp chassis by first removing the two
back panels .
Remove the leather handle and set
it aside with its mounting hardware .
STEP 1
Drill two holes in the cabinet
Two 10-32 x 1 .5" machine screws hold
the metal chassis inside the top of the
cabinet . The mounting hole template
on page 31 shows where to drill the
holes for these two screws .
The holes you're about to drill line
up with holes on the chassis, to the
right and left of the print control area .
Compare this template to the mount-
ing holes in the chassis, and you'll see
how these holes line up .
Cut out the gray area and fold the
template on the dotted lines . Center
it over the control panel cutaway,
aligning it with the back edge . Tape
it in place .
Press a sharp awl through the tem-
plate at the screw locations to create
a starter hole for drilling .
Drill two 3/16" holes through the
top of the cabinet, keeping the drill
square to the surface .
Reinstall the leather handle .

STEP 2
Mount the power cord clamp
Drill a 5/64" pilot hole to mount the
nylon cable clamp . Locate the clamp
on the left wall of the cab-
inet, near the lower-left
corner as seen from the
back, 2" from the bottom .
Don't drill through the
cabinet! Use a piece of masking tape
on your drill bit to mark the depth, or
use a StewMac Depth-stop Drill Bit
(item #1712) .
Use the black cable clamp screw to
mount the cable clamp . You'll secure
the power cord with this clamp later,
during final assembly .

STEP 3
Solder the speaker leads
The speaker leads are black and white
wires with vintage push-back insu-
lation . Twist them together to keep
them neat .
Push the insulation back 3/8" and in-
sert the white lead into the speaker's
Back
positive terminal and the black lead
through the negative terminal .
Before soldering these leads, place
a business card or other protection
under the terminals to prevent sol-
der dripping onto the speaker cone .
Solder the two leads to the speaker
terminals . See "Tips for great solder-
ing" on page 16 .
