Section 1: About This Manual
This manual gives the information needed to build and use Akitika LLC’s PR-101NR
Stereo Preamplifier. The NR version costs less than the PR-101 as it omits:
1.
The remote control
2.
Motor pot for volume and associated components
3.
Motor pot for balance and associated components
Who Should Attempt this Project?
You can build this kit if you can:
1.
Solder (using normal rosin core solder and a soldering iron).
2.
Use simple hand tools like screwdrivers, wire cutters, and pliers.
3.
Read and follow directions.
It helps if you:
1.
know a bit about electronics, or
2.
have a friend who knows a bit about electronics
3.
can get to YouTube to watch a few helpful videos about the assembly process
(none are posted as of this version of the manual).
Tools you’ll need
You’ll need the following tools:
1.
Phillips screwdriver (#1 and #2)
2.
Pliers or nut drivers suitable for #4 and #6 hardware
3.
needle nose pliers (helpful, but not strictly necessary)
4.
pencil type soldering iron of 25 to 50 Watts (no huge honking soldering guns or
blowtorches)
5.
wire cutters and strippers
6.
multi-meter to measure power supply voltages and confirm resistor values
(strongly recommended)!
Helpful Tools
These tools aren’t strictly necessary, but make building the kit easier.
1.
magnifying glass, if you’re over 42!
2.
lead bending jig to form axial component leads to the correct span for insertion in
the PCB.
Project Overview
The project consists of the following steps:
1.
Building these circuit boards:
a.
Power Supply
b.
Controller
c.
Input Selector
d.
Volume/Tone Control
2.
Install and wire the circuit boards, switches, connectors, and power transformer
into the chassis.
