The new Quicksilver Phono Preamplifier offers high gain, low distortion, low output impedance and both active and passive RIAA equalization. Input impedance and capacitance are internally switchable and the power supply includes 2 chokes and five stages of filtering. The circuit is all tube, no transistors. Gain is 47db at 1 KHz; 67 db when used with the Quicksilver Moving Coil Step-up Transformer.
The internal circuit board has a switch for impedance selection(47k or 10k) and a switch for capacitance selection(470pf or 270pf). Because of the 600 ohm output impedance of the phono preamp, short cables are recommended between the Phono Preamp and the Line Preamp.
