Yes.

I use a restored/rebuilt Heathkit C-3 which is quite ancient, but 
does the job.

However, there are better (in the sense of more capable) 
instruments available. The Sprague TelOhmMike TO-4, 5, and 6 
are excellent, and there are others like them. I think the TO-5 will 
also check transformers, but the TO-6 doesn't. AFAIK, the all the 
TO instruments will reform electrolytics.
