I don't know if you meant service or user manuals but here is a link to 2465B service manual and I think 2430A can be downloaded from Tektronix but not sure.

I see well I'll do another search in my bookmarks....
I know I've seen user manuals for some of Tektronix scopes but I can't recall where, if I find them I'll let you know
