Another Tintinabar can be obtained in the world of Balance. Once getting the Airship and at least 3000 GP to spare, fly to Mobliz and read the letter from Lola to the soldier. Then, send one for him to Maranda. Fly there and talk to Lola. Fly back to Mobliz, stay at the inn, and another letter should arrive. Continue to do this, eventually send a letter, a record, some tonic, another letter, and a Book. After sending the book, sleep in the inn one more time, then talk to the soldier. He will thank you for sending all the items in his name and give your character another Tintinabar.
