What years was the CS400 produced?

Thanks!

Also, what is the rated efficency? I tried to find some archive info on this site, but so far have been unsuccessful.

BTW, it's cool to see people keeping the 7's and 10's alive. I spent many hours listening to my vinyl through my 7b's.

Years built? I'm not certain.
