Prepping The Boards - StewMac ’64 REVERB UNIT Assembly Instructions Manual

Prepping the eyelet boards
This circuit is built on two eyelet
boards . Signal processing happens on
the main board, and a smaller board
holds the filter capacitors .
For each eyelet board there's a blank
board of the same size . These blanks
serve as insulators to keep the eyelet
board circuits from contacting the
metal chassis .
The pairs of boards mount to
the chassis with machine screws .
Mounting holes are already in the
eyelet boards, but you'll need to
drill matching holes in the insulator
boards .
STEP 5
Tape the boards together
Noting the eyelet holes, align each
eyelet board with its insulator and
tape the paired boards together .
STEP 6
Drill the insulator boards
The mounting holes are pre-drilled
in the eyelet boards . Through them,
you can see the undrilled insulator
board taped behind . Using the holes
marked "M" on the drawing above as
a guide, drill through the insulator
boards with a 5/32" drill bit . Set the
insulator boards aside for later .

STEP 7
Number the eyelets and holes
These instructions will refer to the
eyelets and holes on the main eyelet
board by number and on the filter cap
board by letter . Use a pencil to mark
these numbers and letters onto the
boards as illustrated above .
The main board will be mounted
inside the chassis, and the filter cap
board will be mounted on the outside .
In the photo above, we've positioned
the empty boards just to show their
eventual mounting locations .
