Saba Freiburg WIII

I am restoring this Freiburg WIII and I notice some of the lamps which illuminate the push keys are burned out. Does anyone know of an online site that sells these lamps. They are much smaller than the regular dial lamps. Thanks for any help.

here we are!

Thanks for replying. No, the links you gave me seem to only show the larger type which are used primarily for the the dial ilumination. I just thought that someone here may have found a source for the much smaller lamps which illuminate the keys on my Freiburg WIII from 1952.

No, no - they have 5.5 - the small ones! The bigger for the glass dial are 10!

Yes. Thank you. I can see that now. They just might work. Thank you for your help.

After looking at the schematic for the Freiburg WIII I noticed that there are 3 speakers on the drawing. However , I see only 2 large speakers in my radio. Was there diferent versions of this radio made?

The Tweeter is in the middle of one speaker!;)

Thanks. I did suspect something like that because I saw a wire leading underneath the speaker. Things were done differently in those days. The other thing I noticed was the fact that there are 3 transformers. The power transformer; the output transformer and another one that seems to be associated with the audio filtering system. This is the first radio I have seen that uses a transformer as part of the circuit. Thanks again for your help. John

The capacity of the tweeter capacitor (1µF) had been wrongly calculated. I did it with my CAD and it said: 3,3 µF. It works pretty good now.

Thanks again: I'll try that to see how it changes the sound.

I have a question about the schematic. Have any errors been reported on it. I found two 10uf electrolytic capacitors in the radio while the schematic shows only one .
