Full bridge rectifying use for ultra-fast diodes followed with 8800uF filtration bank. Voltage regulator is fully discrete. No operational amplifier is used. Voltage reference is TL431. This all result in very low noise and perfect regulation. In many aspects it also over-performing battery power supply. Ripple voltage is lower than 1 microvolt! Voltage accuracy is better than ± 0,05%. The temperature drift is beyond every level of standard power supplies. LPS is Dedicated for E.A.T. phono stages and turntables.
