CONSTRUCTION INFORMATION
|
Shown above is one section of the perfboarded
circuit. The preamplifier is on the right,
then the B-format matrix, followed by the output
amplifier. Except for the matrix connections,
the four sections were identical. A portion of
the back of the board is shown above right.
|
Building the tetrahedral (below) was the most
challenging process. Soldering a new corner
melted previously soldered wire joints. Using a
clamp (middle) was not possible for the final
assembly nor in attaching the support wire from
the tetrahedral to the connector.
