Sansui G-7000 needs a good clean up, Heights-Houston Tx

A friend gave it to me, he had it boxed in his attic for 25 years. Looks great, works fine, just want a good tune up, in a reasonable time, willing to take trade for working on it (Realistic STA 78) works fine. Any suggestions. No Heights vinyl or Chuck Roast please. Vinyl Edge, I mean. I am brand new here. Just got tired of not being able to relax and listen to my music again, starting to accumulate nice vintage jewels.
