The amplifier was recently fully serviced. It comes from a private collection that has to be reduced for spatial reasons. I have purchased it from the start for personal use with very strict criteria and it's been maintained by a qualified technician, with the aim of being at 100% of its factory performance. The photos in the ad are of the actual machine for sale. Please see them carefully as they are part of its description.
