Below you find a part of the tube collection Christian Walldorf.

I am interested in old radio technology. I was into electronics as a boy and I want more knowledge. I have begun to repair microphones and radios and now I have two old tube radios from Serbia and Czechia and I want to learn more about them and try to repair them. Thank you.
