Exactly the same thing can be said for every part of literally everything man has made. It all fails eventually. Even stone axes will fail.The 465 and 475 ( and 485) scopes were pretty state of the art when the arrived. Like anything of that nature they need occasional maintenance and repair. They are still held in high regard today despite being a 53 year old design. And some, like mine are still 100% meeting their specifications. Do you think anyone will give a gnat's fart about a TDS1012B 33 years from now?

What on Earth are you gabbling on about? I responded to something very specific.
Yet, even something with no apparent weak links in its first few years turns out to have one very specific one in the long term. I find that interesting.

I find that interesting.Like I said, they were close to cutting edge devices. They employed new technologies that were not yet matured. Evolution of this sort should be expected. In fact, it may have been brought on by the hard use these generally got. They were run until they failed, not replaced every 3 years in favor of newer gizmo loaded units. I don't find it very strange that machines like these eventually fail in specific ways. It's just the sort of thing that ends up happening to machines that are used until they fail.
Normally much longer.

In those days the amortisation period for capital purchase accounting purposes for new test equipment was at least 5 years. Pretty much every piece of equipment, except probes and accessories, was expected to be in heavy use for at least that long. Normally much longer.
Hi All, I ended up picking up this Kikusui COS6100M for $70.00 locally. It seems to work. Now I have a lot to learn. Thanks everyone for your help.
Not least because the purchase price for a run-of-the-mill decent scope was probably the same as an engineer's annual salary
