Identification of a radio device

[97paul]

Hello everyone, I hope someone can help me. Does anyone know which aircraft this device came from? It must be from WWII. I would have guessed B-17, but unfortunately, I haven't been able to find a comparison photo anywhere. The display is very similar to the radio compass on a B-17.

I still have almost all the tubes here.

I have no idea where it came from. The previous owner has unfortunately passed away.

Greetings from Germany
Paul

Not too many controls of the front panel there. But the front plate looks quite similar to the BC434-A control box of the radio compass AN/ARN-7unit while the interior looks similar to the one of the Radio Compass Unit BC433C Bendix MN26C. However looking at the plug seen in your pic I would say there could be somebody who combined the two devices leaving the basic options for location and adjusted it to a home working.

Here the control unit ...

Es gibt nicht allzu viele Bedienelemente auf der Vorderseite. Die Vorderseite ähnelt jedoch stark dem Peilgerät des Funkkompasses AN/ARN-7, während das Innere dem des Funkkompasses BC433C Bendix MN26C ähnelt. Betrachtet man den Stecker auf Ihrem Foto, könnte man vermuten, dass jemand die beiden Geräte kombiniert und die grundlegenden Standortoptionen beibehalten hat, um sie für den Einsatz zu Hause anzupassen.

Hier die Steuereinheit ...

Thank you for the information!
I've since discovered that the device has been converted to mains operation. The plug in the photo is from the Wehrmacht (German armed forces).
Someone must have gone to considerable lengths to fabricate the front panel.
It would be very interesting to know whether this conversion was carried out before or after the end of World War II.

I think this modification was made after the war by some amateur radio operator. Maybe you remember the 'Fox hunting' , a common term for a sport discipline also known as amateur radio direction finding (ARDF), which involves detecting the location of hidden radio transmitters. It was a very popular activity in amateur radio clubs at that time. As memory serves the converting of the militray stuff from demobilization has been very popular in the radio-amateurs untill today.

That could very well be it. Let's see if I can still find the circuit diagram online. Then maybe I could get the device working again. I have all the tubes, but I think I'm missing quite a bit more.
