Dear Rudolf,

I am waiting the new schematic. The wave switch of my device it is not compatible  with any other schematic downloaded from Radiomuseum.

I want to thank you one more time and I am waiting the new schematic.

Best regards,

Dear collegues,

I am now working at an reconditioning of an radio device Blaupunkt 4W65 Holz. Having and reading the three schematics wich are posted on radiomuseum, I observed the followings, about the way of closing the contacts from wave changer comutator (interruptor).

A. No1 schematic

No3 Schematic (identical with second schematic)

Wich one from the schematics described above represents the reality?

B. The radio device Blaupunkt 4W65H is equipped, instead if magic eye with an tube with neon OSRAM GJR 3. Can someone tell me wich are the alimentation tensions required for function and how are made the conections at the socle?

In the 3 schematics that I mentioned above , this condenser is coupled different (reffered to the condenser  0,2 Mf.)
