OLD Tektronix Oscilloscope Identification

[John R Retired]

Does anyone recognize this old Tektronix Oscilloscope?

Looks like it says, "Type 531"

Is it worth anything?

Hello,

The one you show seems to be a rack version of this one:

531 - TekWiki

w140.com

The rack version seems to be called RM31.

It's worth whatever you can get for it on eBay, depending upon whether it works or not.

Since it's a rack version it's likely not worth as much as a stand-alone unit.
