TEK RM5110

[MED6753]

Facebook Marketplace score. Tek RM5110 with 5A15N Vertical amp, 5A20N Differential amp, and 5B13N Time Base. It powers up but all the switches on all the plug-in's are extremely dirty. The Volts/Div light is burnt out on the 5A15N. The pull tab on the 5A20N is broken off flush with the plug-in. And the 5A20N and 5B13N are jammed in place and won't pull out. So there's multiple issues to resolve in addition to re-capping the PSU. Should be a fun project.

Interesting. I've never seen a Tek 5000 series in the flesh. They had a wide range of plugins, including unusual ones such as an audio spectrum analyzer and a curve tracer.

Some updates. I was able to get all the plug-in's removed and cleaned all the sticky and dirty switches. The result is stable operation of all 3 plug-in's. Some noted potential issues. With no signal input and the trigger set to "AUTO" there is no base line trace. Rotating the "LEVEL" control has no effect. That will eventually be investigated. Another potential issue is it seems the CRT should be brighter. And I noticed some "double peaking" which indicates a CRT with a lot of hours. I haven't yet checked the PSU voltages or the HV so it could be an issue in those circuits. I will be re-capping the PSU too.

I found all the manuals online. I forgot to mention yesterday that the scope has a property tag from the University of Rochester, NY.
