For auction original Sansui QS-1 owners manual in good condition. I have been cleaning up my work shop and found this at the bottom of one of shelves. The manual has marks and stains on the front and back covers. Pages 1 and 2 also have some scuff and stains not as bad as covers. The interior pages are excellent including the fold out. Nice manual if you have one of these units and the instruction, also good for other Sansui Quad units from this era, manual explain the matrix system and speaker set ups. Not rips or tears. Sold as is no returns. Any questions feel free to ask.
