Rare Class A stereo preamplifier in very good cosmetic and operational condition. It does not appear to have been modified or upgraded, but I am not the original owner. All inputs, outputs, and controls are functional. Sprayed DeoxIT on the Volume and Balance pots. This boutique preamplifier sounds clear, fluid, and powerful. Note: Phono input was not tested. Shipping: Unit is bubble-wrapped and double-boxed, with extra padding around the corners.
