nora: K42N ; identity

I recently acquired a Nora k42n of which I cannot find any information. First, this radio is equipped with 6 tubes: Visseaux 6C5 metal tube, Valvo 6L7, Valvo 6F7, 6H7?(may be a different number), Valvo89 and a Valvo 89 in the power supply. 5 out of the 6 tubes are glass tubes with the heater connection on top of each. The radio is AC mains only. The speaker grill is on top and the glass dial on the bottom to accomidate the length of the Valvo tubes  I can't find a power switch unless the volume control is also the on/off switch. There are no schematic, labels or tube layouts on the case or back, but there is evidence of them at one time. So my problem is I don't know if the tubes are correct for this radio or in a different order. The radio looks like it was factory made and it was neatly done. I am guessing that this radio was a either a prototype or it was assembled near the end of the war with anything that was available. Since it has 6 tubes in it I'm thinking it was an early model or one designated for a location that was easy on glass tubes, or metal tubes were not yet available. Somewhere it was painted an ugly green color over the original dark grey.I found a match for the original grey and I will return the radio to it's former condition. I would like to restore this radio to at least the proper tube positions( meaning I want to still use the glass tubes) I will settle for a display only piece, but it would be nice to have it play. I am not versed in wiring and electrical repair. I have a fellow collector that is my savior. I however do the wood restorations rather well. Any information or guidence will be a big help to me Thank you.

Please view photos, otherwise nobody can not say anything.
Even the label is important.

Best regards WB.

After considerable effort and many failures, I have been able to upload 1 photo to the forum.Hopefully when I recover, I will be able to load a few more. At least you will get an idea of what I have. There are no paper labels anywhere on this radio. It looks like they were removed long ago. If only?

Hello Wolfgang,  I checked the photos under the k42n Kasten and found my photo. It's the last one on the bottom right. It will take me awhile to figure out how I got the first one as my computer has other problems with software that is undermining my efforts to send photos to this site. In the meantime, could I send to you a disc with all of the photos on it? There are 19 in all. This way I can be sure that you will have them. You can edit them as you please in any way that would help me in my search for the information I need.    Thank you in advance for any help that you can give.    Garrett

Hallo Garrett,

Your device is not in the original version.
The chassis has been put down and adjusted the tube fitting to existing tubes.
See also this post ==> Nora K42n. Unfortunately, in German.

Hello again Wolfgang,   I am so sorry to be a pest. I agree that the chassis was moved down to let the glass tubes fit in the radio, however I still believe this was done at the factory or one of the original engineers that designed the radio. On the page where my radio is, there is a photo of a similar radio with the chassis lowered, that is owned by Reinhard Hanschke. There seems to be a few parts missing on his radio. His radio may have had the chassis lowered after the radio was built.It has the 5 tube line up. My radio has 6 tubes, and when it was built, there are brackets under the chassis that secure it. The brackets all look professionally made. I carefully peeled back the paper tape that secures the loop antenna and found no evidence of the chassis ever being in the groove that it would be slid into. Maybe I am missing something. It would be wonderful if I could read the thread by Reinhard Hanschke, but I have no German skills. Maybe someone else at this site may have some ideas about this radio. I also checked the date codes on the Valvo tubes and they all were made in 1943. The metal 6C5 looks much more recent. It has no date code on it that I can see. I used to be a private detective and it is probably showing. I always keep on digging. There is very little about this radio on the web except for Ebay listings. And they are no help to me. Perhaps there may be a book on German radio history in English that I can buy? I didn't pay that much for this radio, but I am willing to spend hundreds to find out about it.  Thanks Again, Garrett

Hallo Garrett,

No manufacturer would do so.
Look at the socket, the adapters are available for the other tubes. This is not a stable design for a portable device.
Original are 1.2 volt heater tubes.
Now you have 6,3 volt tubes in your model. Here, the circuit must also have been rebuilt.
This is not original.

Regards WB.
