Commentary
A preamplifier with a simple configuration that thoroughly pursues transmission characteristics.
The internal structure consists of only an equalizer amplifier and a buffer amplifier.
The equalizer stage consists of eight low-noise tubes and consists of a two unit amplifier, a direct-coupled differential type. The RIAA equalizer is a CR type, sandwiched between the stages of the unit amplifier to ensure accurate gain distribution and eliminate coloring.
