My passion is vintage audio. In my retirement I like to restore receivers,amplifiers,tuners and pre amps made by Marantz , Sansui,Pioneer and Yamaha.Some I keep others I pass on. Restoration of a piece takes on average 20-30 hours,but it keeps me happy and when I am done the piece is as good as new or better. Just send me an email with the make and model and we can go from there. My wife won't be happy but I will! ps I only work on my own pieces,sorry!
