Definitely DO NOT use Tung Oil. If you want to clean it, just use some Kotton Klenser or the pumice free versions of GoJo or GooP hand cleaner. Then something like Howard's Feed 'n' Wax or Kotton Klenser's Protective Wood Feeder or their Lemon Oil and Beeswax polish will give a beautiful shine. For the nickel plated parts like the tonearm etc just a gentle polish with Nevr-Dull should be all you need. If the machine has been serviced properly there should not be much else to do.
Enjoy!
