My contribution to the list --
Television Engineering Handbook (Revised Edition)
K. Blair Benson, Revised by Jerry Whitaker
I picked this up for a meager $25 shipped used.
It's huge and I think it's well worth it. I've paid more for used textbooks in college with less information in them!
A lot of useful information, even some theory that can be applied for amateur radio use.
Any others?
