Father in law passed away, and selling his system... EAR 864 PreAmp in Very Good Condition. The EAR 864 preamplifier is designed to meet a wide variety of needs. It is based on the circuit designs used in the highly successful EAR 834P phono stage and 834L line preamp, with a few additional refinements and features including balanced outputs and one balanced input, all coupled via high quality transformers. It has facilities for one phono input (MM/MC) and five line inputs, and offers a genuine tape monitoring circuit, making a total of seven inputs. A high quality volume control is fitted, as well as a panel mounted power switch. Input and output terminals are gold plated. The EAR 864 is the perfect match for any high end system.
