When your old-school electronics are out of order, it is time to complete a few repairs. A common repair is the replacement of the tube and tube socket. The tube socket functions as an electrical socket. Without a working tube socket, your radio or amplifier has no power. Although the repair is fairly simple, it is important to give consideration to the parts that you select-- an authentic replacement part, such as this Svetlana 5U4G vintage tube and tube socket. Using original parts helps prolong the time until your device's next tube replacement. Once your new tube socket is in place, spend an evening relaxing with your old radio or enjoying your vintage amplifier.
