I have Nordmende Turandot in my office from about 1958/59. I could only find the chassis shot which shows this small table radio has three count em three tweeters
This model has a couple of extra buttons that activate the tweeters in differing ways called 'Presence' and 'Brilliance'. I usually have it on low in the office and the extra high end emphasis is great.
Looking on radio museum your model was made between 1957-63, has five tubes and puts out about 3watts.
The only thing I noticed with this vintage of Normendes is they started using sections of circuit board on the chassis rather than a solid steel chassis deck. A way to save money I guess. As you get into the sixties the models started incorporating ceramic capacitors and diodes in areas that they weren't used in the fifties.
