I had a pair of the early 770's with the clear Peerless woofers, they were my first "proper" speakers. the Seas tweeters in these are pretty damn good, you can find the specs on Seas website who have all the specs for vintage drivers. I sold mine and not have Mission 720's, Mission's top of the range speakers at the time, also have a pair of 730's that have had the tweeters and very hard to find Celestion MF mid drivers removed. I rebuilt the 720's from scratch, the tweeters were blown and the mid/woofer drivers surrounds had gone. also recapped the X-overs which if like mine are glued to the speaker cabs and take applied violence to get em unstuck.
Your drivers look original, there's a lot of threads out there that state these tweeters are ferrofluid, they're not. Have you checked the fuses Rob to see if they have the correct rated fuse and not a six inch nail or similar? From memory mine had loose fuse holders. You can't beat big speakers but the size can be a problem obviously especially with wives.
