A few nice hp photo images I found:
HP 5083-0722 CRT

The display on my 1960s-vintage Hewlett Packard 132A dual-beam oscilloscope is dead, and I suspect the problem is the CRT tube. But before I can search for a replacement, I had to get the part number. And to get the part number, I had to poke around inside.
Now I know, so If you happen to have a spare HP 5083-0722 CRT tube on hand, please give me a shout.
