This website link is all things Braun and should have something of help-
http://www.radiodesign.de/
check out the fifth link up from the bottom of the menu that should appear on the left side of your screen. It says Rad.-Pho.komb
You can use a site such as babelfish to translate.
I think one of the coolest aspects of the Braun radios is their design was about ten years ahead of the times. If you look at that radio you think that style looks mid sixties but the tuning eye is the tip off of its true mid fifties error. I have TS1 in need of restoration. They have very high quality Isophon speakers.
