How about a vinyl or CD of Tchaikovsky's music? You could also consider getting him tickets to see a Tchaikovsky concert, or a biography about the composer. If he enjoys reading, you could also get him a book about Russian history or culture, as it may offer insight into the era Tchaikovsky lived in. Another thoughtful option could be a painting or print of a landscape from Russia, as Tchaikovsky's music was very influenced by the country's scenery and atmosphere.
Or you can get him a star map with the date when he was born.
