This PDF is a scan of three original Tektronix manuals, those being the service manual for lower serial numbers (249999 and lower), that for higher serial numbers (250000 and higher), and the operating manual for all serial numbers (and the Tek 475 as well). This is our tenth year in the scanned manual business, and AA4DFs products are known worldwide for high quality and for being complete.

Please note that we have literally thousands of PDF manuals available. We specialize in electronic test equipment manuals but do have others, plus a considerable number of general electronics texts, references, handbooks, and etceteras. We distributed these on the largest auction site for ten years before their greed and disgusting anti-vendor practices compelled us to close up shop there. The majority of products listed on our web-site, aa4df dot com, can be brought here for your consideration at your request.
