Alieno Twin Chassis Tube Phono Stage with DC battery powered supply
ALIENO Phono Preamplifier is a tube phono stage for Moving Coil cartridges.
It has three gains available (66 – 60 – 54 dB), easily selectable by a jumper after opening of the upper panel.
Cartridge load setting by blind Rca plugs on rear panel. Overall internal impedance of phono stage less than 250 Ohms, for perfect matching also with very low impedance (from 2500 Ohms up) line preamplifiers.
Power supply in a separate cabinet with Virtual Battery Powered technology. Two Rca inputs selectable by a switch on rear panel, RIAA equalization, Rca and XLR outputs
