I had to repair a couple blown speakers in one of our Peavey cabs (that was quite a gig!) and could find no schematics online. Since it seems like a popular speaker cabinet, I figured I’d post what I figured out for others to use. Hope it’s useful – please leave me a comment below if it is (or even if it isn’t) so I can see if posting this was worthwhile to anybody.
