SECTION 1 – Mount ¼” Jacks and Terminal Strip Componets
Please refer to DRAWING 1 and DRAWING 2.
Orient box with two 5/16" holes on top and ½” hole nearest you.
Mount input jack in 3/8" hole on left side of box with hardware provided.
Washer goes under nut on outside of box. Make sure center solder lug
of input jack is facing up. Correct positioning of jack will make soldering
connections much easier. When positioned correctly, tighten nut.
Mount output jack in 3/8" hole on right side of box with hardware
provided. Washer goes under nut on outside of box. Make sure two
solder lugs are in most upright position before tightening nut.
Mount the 8 lug terminal strip to the two 9/64" holes as shown in drawing
2 using #6 hardware. We will refer to terminal numbers as illustrated
below when connecting components.

Terminals #4 and #6 will have more than 3 components/leads connected to
them. Because of this we will use both the upper and lower portion of the
terminal.
Terminals #1 & 4:
220K resistor
1) Mount the components and leads to the
lower set of holes
, but do not solder.
Terminals #4 & 6:
1M resistor
Solder the lower terminal hole connections on
Terminals #1, 4, 5

now.

Connect and solder all of the following to their respective terminals as listed. (Make sure none of
the component leads are so close together that it could lead to an unintended connection).
Be
careful not to overheat the MPSA13 transistor when soldering.
Stripping and tinning wire:
Throughout these instructions you will be told to strip and tin a length
of wire numerous times. Unless noted otherwise, cut the wire to the length stated in the
instructions, then strip ¼” of insulation off each end. Twist each end of the stranded wire and apply
a small amount of solder to each end (tin the wire ends). This prevents the stranded wire from
fraying and makes soldering much easier.

The remaining components and wires can be connected to the upper portion of their respective
terminals. Unless otherwise noted, “mount” means to mount the component, solder the component
in place and trim the leads.
