In Part 1 of this article, I detailed the theoretical
background to the design. This part will detail the practical build process of
the circuit as well as the enclosure.
The Circuit
The idea of the circuit is to use an input buffer,
a step up interstage transformer for gain, and an output buffer. The circuit
used for both buffers is a modification of the so-called Diamond Buffer that
utilizes a servo to control for output DC offset. Everything is DC coupled.
