Detailed view of the power supply chassis. In this receiver the power is built on another chassis, this to improve the Signal/Noise ratio.

Power supply bottom view. You can see the big filter capacitor and the tube socket.

 

Picture of the receiver chassis from the top. On the right you can see the magic eye.  This is the tube used to check the stations fine tuning. Unfortunatly during the restore I have not found the exact type of tube, so I had modified the socket for the new one.

Bottom view of the receiver chassis, from the component side.

Amplitude modulation tuning assembly. Inside a receiver as this with 9 (nine !) bands on short waves you can find a very complex tuning system, like this one.

 

View of the large internal speaker. I placed my hand in order to understood the real size od this component.
