Section1: Introduction

Thank you for choosing the L2 Pre-Amplifier Kit from AudioNote Kits.
We hope that your build experience will be a satisfying and rewarding one.

General Information

Should you encounter any problems with the kit, please call AudioNote Kits on 613 822 7188 or via e-mail to
audionotekits@rogers.com.
Please read through the assembly manual fully to familiarize yourself with each stage of assembly before starting
construction. Also read each individual section thoroughly before and during construction.
This manual has been presented in a simple step-by-step manner following a logical method of assembly.

Preparation

Before starting assembly, open the packaging and familiarize yourself with the components and compare them with the
parts list(s) provided in the manual. Take sufficient time to become really familiar with the parts, as this will help prevent
any confusion later. Don't worry if you cannot read the resistor values from their color codes, for we have prepared a chart
toward the end of the manual to help you differentiate the values. Alternatively, a web-based resistance calculator is
available on the AudioNote Kits website.
Upon inspection of the parts, you will notice that in particular the electrolytic capacitors and rectifier diodes are polarized,
that is, have a plus and a minus terminal. These components must be inserted correctly, otherwise serious damage to the
kit could occur.
The electrolytic capacitors have the plus and minus identifiers marked on them. The rectifier diodes have their polarity
indicated by a light colored band on one end of the body of the diode, which is always the cathode end of the diode.
The following tools are required to assemble the kit:
1. A soldering Iron, preferably 15 to 35 Watts power, with a small chisel tip (approximately 1/8" or 2.5 mm). Also, an
accessory stand with damp sponge for cleaning the soldering iron tip is recommended. It is appropriate to note
here that we do not provide solder with the kit. We recommend a rosin core flux solder, NOT acid core, such as
"Kester 44". An even higher recommendation is AUDIO NOTE corrosive-free silver solder, which you can
purchase from Audio Note.
2. Small and medium size Philips head screwdrivers (No.1 and No.2 size) for the 4-40 and 6-32 machine screws
respectively.
