I have found one of these old o-scopes and it would seem that it is in pristine condition except it does not power up.
the electronics look to have never been powered up. I think maybe it was built as a kit, it did not run and was stored away for God knows how long. still had protective film on front panel and all probe attachments in perfect vinyl pouch. I need the documents for it ie schematics and manual so I can repair it, but the link sited below is now dead and no such documents on e-bay. Can anyone help. Quote:

Sorry for the bump, I know its generally a no-no on most forums, but i need the contained information as well, and the above link was my only hope on a few occasions so far with no luck whatsoever.
