Here is a fully restored 1941 Zenith Tube Radio Shortwave Model A248739. This was covered in 50 years of dust, chipping and warping and after three months and layers of wax, stain and a new belt for the robot dial it is now a living room piece from a lost era. This was called a long distance radio and you will see why when you see the video. It has a 12 inch speaker that puts out a bold sound and an awesome internal antenna.
Thanks to Johnny4903 for the video.

EMC Engineers have long known that Powerline Networking adapters cause unacceptable interference to radio and breach the European EMC Directive since they do not comply with the Essential Requirements.
