For a RIAA preamp it’s very important keep a short path for audio signal from input to output. Otello is a tube phono preamplifier, zero feedback circuit with an ultra low noise tube-hybrid power supply. Otello use a passive RIAA network, only one high quality coupling capacitor in the entire signal path and a star ground circuit with separate path for signal and power supply. Two choices are available for gain: 42 dB for MM cartridge…
