5 Step-by-Step Instructions
The following steps are recommended for assembly of the 20 W Stereo Amplifier. As each step is
completed, check it off the list. The project is divided into four major elements—assembly of the
amplifier boards, assembly of the preamplifier power supply board, assembly of the power
management board, and assembly of the chassis. Builders are encouraged to follow the specific
instructions provided in the following sections.
An examination of the shipping box will show that the parts for each sub-assembly are
contained in separate boxes. It is recommended that only one set of components be opened at a
time as this will reduce the possibility of component mix-ups.
Each section heading that follows marks a logical start/stop point in construction of the
amplifier. Do not rush through the project; instead, consider setting modest goals for progress
over a period of some days. A more relaxed pace often results in a better end-product, and a more
enjoyable overall experience.
Organize a work space that provides ample room and light. The following tools are minimally
required for assembly:
• Common screwdriver
• Phillips screwdriver
• Wire cutters
• Pliers
• Long-noise pliers
• Solderless terminal crimp tool
• 25–35 W soldering iron
• Solder
• Heat-shrink gun is recommended, although not strictly required.
While there are certainly a number of approaches to building a vacuum tube product, the
following procedure has proven to be efficient and repeatable.
