Vintage Zenith Tube Radio Model G730. Amp Only No Housing
Taken out of the housing it was in. It needs a 3ohm speaker as far as I can tell from research and a housing.
If you plug it in all the metal is live 120v(the metal housing). The back must be on for it to work. Needs some contact cleaner and probably some new components (caps etc). The tubes glow when it's on which is cool.
