Engineered to excel with both MC and MM phono cartridges, the Doshi Phono Preamplifier includes a Moving Coil Pre-Preamplifier whose J-Fet transistors provide 26 dB of gain, followed by a pair of monaural, 2:1 step-down transformers which lower gain to 20 dB. Although MC head amps often use step-up transformers (i.e., to increase gain) our novel use of step-down transformers accomplishes three critical benefits: Provides Galvanic Isolation, keeping Pre-Preamplifier grounds separate from the rest of the preamp Converts balanced cartridge input to single ended output, enabling our “Zero-Feedback” tube circuit Impedance is stepped-down 4:1, providing increased bandwidth and a low impedance output to drive the tube MM section.
