Congratulations GS, real nice looker, I own one myself as well so I know how good it sounds! Actually found my 7979 in the dump of all places, I have an ongoing thread on how I'm fixing a few niggles with it, in pretty good shape, and near 100% working now too.
I'm amazed how sought-after these are, every time someone gets one he becomes a celebrity and gets so many offers! Enjoy it, those 8" drivers sure put out a lot of sound! As my Dad says, if you want bass, the speaker has to be big, simply a physical law, no ways around it. He's got a pair of 15" drivers in 4 foot by 4 foot folded horn cabinets, goes down to 16 cycles lol.
Cheers!
