I'm a student and while I was looking to get a proper oscilloscope, I ran into this Craigslist post for 4 oscilloscopes for almost nothing, and I took the offer. Two of the scopes ended up having issues (a Tektronix TAS 455, and a Tektronix 2225). The 2225 appears to work in every respect except for the trigger and the trace position knobs were gone. I was wondering what you guys would do with it if you were a broke student. Would you sell it for parts on eBay, or perhaps attempt to make a repair, or maybe use parts of it to build something interesting?

You should be able to get at least one of them going. There is a Tek 2235 repair thread that may help you https://www.eevblog.com/forum/testgear/tektronix-2235-repair-thread/ (https://www.eevblog.com/forum/testgear/tektronix-2235-repair-thread/)

2225 and 2235 are completely different scopes.
2225 is much easier to repair so repair it and use it. It's a very nice scope and mostly made of standard parts. People will help you solve the issues on here. If the knobs are broken off at the shaft then I'd scan ebay etc for an entire front panel or a parts machine to steal them off. If just the knobs are missing you should be able to find some to replace it with.
That's 1000x times better than my broke student scope which was a 5MHz single channel job.
