I've just purchased my first vintage amp, a 1970 Vibro Champ. It has its original speaker and it sounds great. In a number of threads I've read recommendations to remove and set aside vs leaving the original 45+ year old speaker installed. Seems like there a number of arguments to both sides. Arguments for removing the original are having it intact for resale and the fact that it might not sound as good, in its old age, as it once did. Leaving it in of course allows you to play and listen to a true vintage amp. I'm leaning towards replacing it so at the very least I can compare the sound to the original. Just curious is there a consensus, do most of you leave in the vintage speakers or take'm out and set them aside? I haven't seen a thread on this subject, just comments here and there in threads on speaker replacement recommendations.
