Taking a chance on an untested chasis

[kschrief]

Long time lurker, first time poster, beginning collector!

I'm in talks with someone to possibly pick up an early 60s RCA Victor New Vista (https://us.letgo.com/en/i/vintage-rc...4-34bf252ad7c4). I only want the set if it works, or is simple to repair/get repaired. but the power cable is missing. According to the owner, it worked several years ago when last powered on.

My question is, could any horrible damage have occurred in the last few years lying dormant that would cost a very large amount to repair (>$100)? I have enough electronic knowhow to grab or make a new plug, but the little I do know about CRT sets is that I don't know enough, and should absolutely bring the chasis for professional repair if it's damaged.

Thank you all in advance for the advice!
