People would kill for your TU-X1 tuner!
Yes mods would help. I had my Sansui done by one of the best Ken @ Stereo Surgeons in Hartford, CT & it sounds worlds better than stock. Ken's a Sansui expert & his pricing is very reasonable & he includes before and after specs. If you don't want to mod it you must get it re-aligned. I would still get the electrolytics replaced as they don't last much more than ~20 years.
