((( A friend who is a prominent tube amplifier and speaker designer (mostly horns but some box speakers) had Maggies in the 70's and 80's and said that every year, to get them to sound good, he had to open them up and stretch the ribbons. That normal temperature changes from hot to cold, and just normal playing weaken the ribbons and stretch them out. As they stretch, the sound quality diminishes.)))
10 bucks says your friends tubes were wearing down
and he thought it was above.
The new 1.7Is tweeters on outside with Cardas clear Sky will fix you up.
