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.
