I remember a Fry's Electronics had a large Klystron in their store.

Not for sale, just as a kind of decoration.

-The ham radio club I was a member of while in university had a long and proud tradition of sending letters to former members, asking if their employer happened to have any items suitable for donation to the club; power tubes (think 3-500Z, 4CX250/350 &c), old measurement gear, etc, etc.

Back in the seventies sometime, they received notice that a shipment of QRO (high power!) tubes were on their way, courtesy of $COMPANY.

Enthusiasm turned to amazement turned to dismay when it turned out the shipment consisted of several big Klystrons - hardly useful for amateur purposes! We still had one on display when I attended in the late nineties, though.

They arrived in a truck, one coffin sized crate, one slightly smaller. The contents were bright read, and looked like jet engines. - la4rt
