Xiang Sheng 728III HiFi Tube Preamplifier Preamp w/ Remote Control

Up for auction this is a Chinese clone of a Marantz seven. I have changed the rectifier tubes to US-made Sylvania in order to do this. They have to have adapter plugs, which are included. I bought this new two years ago this preamp is an excellent working condition and very good physical condition. It comes with a remote. The tubes have been replaced with 12 a T7 and Psvane ECC81. The upgraded tubes only have 20 hours on them . I will also include the four springs that hold the tubes in place. They are not in the photo .
