If you (the list population) has not read Jim Williams (as editor)
book "The Art and Science of Analog Circuit Design", it is pretty
much a mandatory read, IMO. I suspect most people on this have read
it. The story that Craig relates is Jim's chapter in that book
(Chapter 17, "There's No Place Like Home"), and was the basis for my
decision to buy older, broken instruments and repair them for my own
use. I don't have anything close to Jim's experience with analog
engineering, but I have learned a heck of a lot figuring out how to
fix these things. And some of the design that went into the older
'scopes (I can't remark about the newer stuff) was darn elegant.

Now that's funny!!! I'm not
letting him near any of my test gear... :) That would be a
very good way to learn how to fix these.

Read the late great Jim Williams perspective on fixing stuff. His college
supervisor told him that anything that broke, he had to fix. OK - that was
a decent enough challenge. But then he got into the next level, where he
and a friend would subtly break each other's test gear - then the challenge
was who could fix their stuff the quickest. Hell of a good education on how
to resurrect broken gear. And Jim was a classic era Tek fan - everything in
his test lab was from earlier than the mid 70's.
