This was my former apprentice Jordan’s scope that I got in the package deal when he left town for greener pastures. The 453 is a nice portable scope, and this one is in good working order. It’s missing a foot on the bottom, and the rear stilts are in bad shape, with 2 of them being bolts, but they still do the job. I had a hardcopy manual in my library before I got the scope.

Here’s a link to the service manual: https://www.dropbox.com/s/pm011s8h93ca10u/tek%20453.pdf?dl=0

Let me know if you have any stories about the 453 Oscilloscope, or if you would like to purchase mine at a reasonable offer.
