Here in Brazil I changed ALL the Amiga capacitors since all of them are dying. I have 3 A1200. One of them I buyed exactly when Amiga comes out (nearly 1995) and I never USED it. He was perfect never opened and when opened all capacitors was going to dead. Here I payed U$35 to change all of them. Look if someone can do the same for you.
