In the pictures, the phone looks flatter than it is in reality, now on the table, I like it even better. The connection to a Eumex 800 worked straight away. On the bottom of the phone, you can choose between the pulse and tone dialing. A converter is not necessary. The voice quality is absolutely up to date, the functions it fulfills. Only the bell makes funny business. Either testing the manufacturer with a higher voltage or telephone my telephone system is something little "juice" from. Because of the small bell clapper swings with difficulty until the bell back and forth. If he does not reach it, one hears only a faint buzz. But this happens rarely and is also depending on which pad the phone is. Is it wrong, there is the supplied phone me to said buzz. But even if the phone (as usually) rings, as it should ring, so the volume is naturally not so high that it can be heard throughout the house. That was earlier in the 70's that. The Post even then leased to Hauf additional bells that additionally installed on the wall somewhere in the house. In addition, the Wählscheibenmechanik can compete in any way with the former original Telefonenen the post. These are merely a functional replica. Flair and Feeling in the 70s was totally different. I have here an original off-white mail Telephone from 1972. This feels totally different. Therefore, whoever wants to experience the feeling of the previous years, I recommend an original old phone together to buy the AD converter. Priced comes in the slightly out of the same. Otherwise the Opis 60s is highly recommended. How long will it works tell.
