The companion PSU-1 power supply for the PS-1 Phono Stage and/or the LS-1 Line Stage measures a compact 10 7/8 in W - 2 1/2 in H - 5 1/2 D and weighs in at 2 lb 5 oz. Power consumption is
only 12 watts when powering both the phono stage and line stage. Using the same master power supply for both the phono stage and the line stage not only saves money and space,
it also helps eliminate ground loops by referencing the zero volt reference of both the phono stage and line stage back to one common point.
