There appear to be a few on eBay. Most are listed as service manuals even though they say "instruction manual" on the front. However, looking at listing pictures item 271658505408 looks like the same version that's available on the Tek wiki site that has full diagrams, parts lists, and theory of operation. $26 and free shipping seems reasonable.

Subject: [TekScopes] Tek 555 service manual.
Was wondering if anyone here had a factory service manual for a 555 scope. I have the instruction manual already. Thanks for any time and help.
