I'm posting this tread about my very rare Sansui PM-2020 integrated tube amp which I sent off for a restoration and am looking for advice or suggestions from fellow AKers about what I am going through. Three years ago I purchased a Sansui PM-2020 integrated stereo tube. This model is Supposedly Sansui's first stereo integrated tube amplifier and there are rumored to only be around a dozen or so known to exist. This obviously is the rarest Sansui that I own and wanted a full restoration done to it. Well I sent it of to someone with whom I thought was a very professional audio tech and who had restored one amplifier for me before. After A few months the amp was completed and sent back to me. Much to my dismay, the amplifier was not working when I got it set up and there were very loud cracking and popping noises that sounded like they were on the verge of blowing my speakers. After contacting the person who restored it and discussing the issue, he had me send it back to him. This was in December 2015. When he got it back, I was told that the wiring was corroding from the inside and that it needed to be rewired. I was told it would be a tedious task and it would take about 8hrs to complete. Well it is now officially over 2 years since I sent it back to him and I still have not received my amplifier and even though I had a previous good repore with this tech, he has completely ingnored my emails and dozens of voicemails. Not sure how to go about handling this other than flying out and showing up in person which I just might end up doing. Any advice on getting my amplifier back?
