Thank you very much Tom.
I appreciate very much your answer.

This Metz belonged to my father and was given to me by my mother six months ago, before she passed away. So there is a sentimental value several million times the $40 it's priced in the market. This may be the chance to start in a very exciting hobbie.
As I told you, I want to keep it, but I was surprised to find so little information about Metz radios in the Web, compared to other brands.

Regarding your question, yes, there is a tube list in the back. The codes (from left to right) are: EM34, ECH81, EF85, EAF42 and EL41.
Additionally, it is written 7V 0,3A

I would like to ask your help once more:
This radio was used in a country with 220V AC. Now I am in a 110V country. The radio has a selector in the back (red circle, Picture 1) for setting the voltage.
There are two "brackets", apparently for fuses (picture 2). There is a thin wire welded in bracket "A" (not visible in the picture), while "B" is empty.

My questions are:
1-I think there should be a fuse in "A". What rating?
2-Why are there two brackets? If a change the voltage to 110V, should I use the fuse in "B"?

Thanks

Languedoc
