Hi all,
I noticed a difference between the speaker modules of the Egger and Braun era.
It seems that Egger used an industrial transformer and Braun used an self wound transformer.
Probably this was a commercial decision.
Anyway, the DC coil resistance differs a lot
The Egger has a resistance of 245Ω while the Braun has a resistance of 26Ω.
It seems that these self wound transformers are used till the RWO era.
Here a picture of the Egger (left) and Braun (right).
Many greetings
