Tools and Supplies You'll Need

You'll need the following tools:
1. flat blade screwdrivers for #4 and #6 screws, #2 Philips head screwdriver
2. needle nose pliers (helpful, but not strictly necessary)
3. pencil type soldering iron of 25 to 50 Watts (no huge honking soldering guns or
blowtorches)
4. wire cutters and strippers
5. de-soldering tools (see the Appendix 1 and Appendix 2)
6. Magnifying glass, if you're over 42!
7. A multi-meter for measuring Ohms and DC volts is handy, but not strictly
necessary

Recommended Solder

The kit must be assembled with 60/40 Rosin Core solder. The recommended diameter is
0.032 inches. Among many such sources of solder, I have used Radio Shack part number
64-009. It contains 8 oz. of solder, which is much more than you'll need to assemble this
kit.

Project Overview

Broadly, the project consists of the following steps:
1. Labeling, then de-soldering all the wires from each circuit board.
2. Replacing a number of components from the phono section of the preamp with
the supplied components.
3. Adding a few wires to the circuit boards.
4. Re-attaching the wires to the circuit boards (with a few modifications).
5. Reassembling the preamp.

Important Safety Notes

By purchasing, using, or assembling this kit, you have agreed to hold AkitikA, LLC
harmless for any injuries you may receive in its assembly and/or use. To prevent injuries:
 Wear safety glasses when soldering to prevent eye injuries.
 Always unplug the power before working on the equipment.
 Large capacitors hold lots of energy for a long time. Before you put your hands
into the equipment:
o Pull the AC plug!
o Wait 1 full minute for the capacitors to discharge!
 Remove jewelry and rings from your hands and wrists, or anything that might
dangle into the amplifier.
 If working in the amplifier, keep one hand in your pocket, especially if you're
near the power supply or power supply wires. This can prevent serious shocks.
 Build with a buddy nearby. If you've ignored all the previous advice, they can
dial 911 or get you to the hospital.
