To attempt a repair would result in destroying the cone.
Bill Hanuschak described to me in great detail what it would take to repair the 3000H tweeter. By his account the effort would be very costly, and I didn't get the impression he was even interested in repairing them. To my knowledge ALTEC never repaired them, but tossed them into a trash bin. When I worked at ALTEC I was offered a box full of blown 3000H's on the order of about 50 of them. Naturally, I passed.
A word of advice, take care of those puppies. Don't crank them up for a kegger party. I own an ALTEC 833 Verde that was loaded with the 602B, and unfortunately I found out the hard way just how delicate the 3000H is. It wasn't the volume that killed it. It's demise was the result of a dirty source switch on my equalizer :-(
H.F.
BTW - I would seriously consider loading those speakers into larger properly tuned enclosures. Something on the order of 5 to 6 cubic feet. You wouldn't believe how BIG my Verde sounds.
