Here we have a highly desirable Whest Two Dual Mono Phonostage. This solid state Class A preamp comes with a separate power supply with a toroidal transformer. This phono pre will work with MM and MC cartridges. Simply adjust the dip switches for each channel to the correct load and gain values. If your cartridge requires a value not offered using the dip switches, Whest Audio will be able to advise on how to set up the West Two to work with it. The Whest Two is able to be "trimmed" to work with ANY cartridge.
