Also - sounds like you found the problem, but check your wheels, especially for spoke tension, where you said they're near 25 years old. I had to chuck a wheel with no tension left and corroded nipples (winter bike), and have had other wheels start poking holes in tubes. I'm now better at wheel maintenance - winter wheels barely get touched still, though.
