“The Preamp” features a two-stage amplifier concept as its core principle. The initial stage acts as an input and symmetry amplifier, efficiently amplifying and converting the input signal into a balanced signal in a single discrete stage. This design minimizes signal paths and reduces components that could impact the signal. With its balanced configuration, the amplifier offers enhanced interference protection and significantly extends the bandwidth, all achieved with just one amplifier stage.
The second stage serves as the output amplifier. While it doesn’t provide voltage gain, it acts as a pure impedance converter with ample current reserves. The output stage of “The Preamp” is fully balanced, double mono, utilizing four NOS PCC88 tubes per channel. These carefully selected tubes offer exceptional linearity and high bandwidth, ensuring minimal distortion and a low output impedance. The signal path is exceptionally short.
