Integrated Stereo Tube Amplifier, introduced in 1998. Purchased new and only one owner. It is an excellent amplifier with rich sweet sound and good dynamics. No flaws. The front plate and the transformer covers are polished brass and in perfect condition with no scratches or other defects except a very, very slight discoloration from the heat on one transformer cover. Includes power cord, tubes and extra fuses. The amplifier was checked over and adjusted/repaired as necessary by the manufacturer, Jolida, Inc., in 2016. I prefer local pickup or can meet within reasonable driving distance. If shipped, buyer must pay shipping. I do not have the original box.
