More than 900 different Sansui Literatures on PDF file format! - Please click on one of the following categories to see what are available;

Sansui Brochures Sansui Manuals,  Sansui Bulletins Historical New letters and Technical Publications


Sansui Brochures, Manuals, Bulletins, Books, and Articles in Color

We offer more than 900 scanned images of Sansui brochures, manuals, bulletins, rare books, and articles on Adobe Acrobat Format files.  These images were scanned from the original materials.  Therefore, all information is very clear to read, and if you wish, you can print these pages via color printers as if they were original literatures.  Since images are scanned in color, you can identify every single detail; we don't offer any photo copies that is almost impossible to read in details (please see the image comparison).                       

Once you make your purchase, we will mail your CD (most of the time, files are too large for e-mailing - 20 to 50MB for manuals) out that contains the PDF file (s).  If you need a specific arrangement for something rather than CD or different payment methods, please contact us at support@obsinc.us.     

Key Benefits

  • All of our documentation is scanned from the original materials.
  • Reasonable Price - Our purpose of this offering is not to make profits, but to help people who are looking for the right information that is no longer available because Sansui does not offer any international support/services any more.
  • We use the automated Microsoft e-Commerce Service for our transactions; therefore, your sensitive personal information is absolutely protected and safe.

How does this service work?

  • Please click on one of our Sansui literature categories you are interested in.  This will bring you to our ordering process where you can find Sansui literatures you are looking for.  Pick and choose any literatures you wish to receive.  All PDF files you choose will fit on a single CD.  During you check out process. you will be asked about your payment method; we accept Master Card/VISA or PayPal Payment.  Currently, we use only the First Class US Airmail for the shipping method at $2.50 to anywhere in the world.  Please note that this $2.50 charge will apply any delivery method you choose.     
  • We will NOT proceed the credit card transaction until we actually mail your CD out.  The lead time between your order and the actual CD shipment is usually within 5 business days.  For some rare literatures, we need more time, and if this is a case, we will notify you via e-mails.  Again, you will not be charged until the actual CD shipment takes place.
  • After you receive the information, if you don't like what you see, please let us know about it.  We will fix the problem, or we will send the money back (except the shipping and handling fee).  SATISFACTION GUARANTIED!
