Just read through all the posts here, I did some research on the 7000 since one is for sale here locally. This model was sold overseas-europe and asia, military bases as you noted. One of the big differences at the front is the Eight's do not have a Mic control as the 7000 does, that's where the Volume control is on the Eight. Replacing the Volume control spot, is the middle tone control for the Eight. I have an Eight in for repairs, recap, fixing the right output channel, so I hope it will return strong and true to the name "Sansui".
