McIntosh C-28 preamplifier in very good condition. It has been serviced, works perfectly, and sounds wonderful. Includes our original Performance Verification Report and a copy of the owner's manual.
"New records and tapes with greatly increased dynamic range demanded new low noise circuits. McIntosh scientists developed a new DIFFERENTIAL INPUT CIRCUIT that reduced phono input noise levels from approximately 2.4 microvolts in an excellent preamplifier to a new level of only 1.2 microvolts! The differential circuit has only been used in very sensitive professional test equipment and in medico-electronics. The (C-28) preamplifier will not overload or change distortion for any phono input signal from 2 millivolts up to 500 millivolts. This represents a dynamic range of approximately 3000 to 1 on a voltage basis. This fantastic improvement necessitated extreme care in layout and manufacturing. The signal circuits need careful shielding and wiring with coaxial cable to prevent noise and crosstalk in the preamplifier from destroying the low noise advantages of the circuit."
