Vtg Zenith Trans-Oceanic Wave Magnet World-Band Radio Powers On

Vtg Zenith Trans-Oceanic Wave Magnet World-Band Radio Powers On. Please see the model number in pictures. The unit powers on and I can hear static but I didn't tune anything in clearly. I don't know how to actually use this item to make it sound more clear.

It powers on but I didn't see a glow from a light (it might just need to be replaced but I don't know how to replace the bulb). All knob and buttons work. The antenna looks like it's possibly missing a knob on the tip? It is in its original case that shows ware.
