McIntosh C220 Tube Preamplifier. Absolutely perfect condition. I am the original owner and it has been kept in a smoke free, pet free environment. This unit is an excellent performer and is a joy to use. Very smooth. I'm not going to list the specifications as this is still a current product and the McIntosh web site can do a much better job of explaining things. Will ship in the original McIntosh double box the same day payment is received.
