When a fuse blows it is usually because a chip is shorted. If a new chip shorts it is either defective or you missed something. I would test the resistors and pull both chips, replace the fuse, and check the power supplies at the chips. You can also have bad caps in the power supplies in these sets than can cause problems, but usually, if the chips fail right away, it is a bad resistor or one supply is missing.
