Tektronix 7T11 Sampling Sweep Unit 500 MHz internal, 1 GHz from external trigger

Description

Tektronix 7T11 Sampling Sweep Unit, pulled from a working environment.
Please note, this was pulled from a working environment at Tektronix. It is impossible to test all the features of a 50 year old product. This means one or more features may not work perfectly (imagine a 50 year old car working perfectly!).
Physical condition looks good. In one unit, the fine knob in the upper left is tighter than in the other unit. I have replaced a couple knobs using ones I have which are slightly different from the originals (assuming the other has original knobs).
I do not possess a mainframe that would allow me to test functionality.
