Lifetime warranty on these limited edition boxes!
My experience with my old 1970's 7A box (not a 7AL) is that it works. All of the old MSD units I've had from the 70's work. There are numerous stories about the 6al boxes failing on people, and I beleive that is why they are using the lifetime warranty spin here. I think the older boxes were built better, at a time when MSD was earning its reputation.
As for the magazine blurb about sending out the old boxes...Well I think MSD as a big advertizer would not have been happy if they promoted the product in a way which would put a negative spin on the current offering.
