Well I got it to work.. On the Marconi there is a sort of small battery in side the chassis and i jusr put a clip across the terminal to connect the circuit and everything works fine now.. I will just remember it for the future.


Those are biasing batteries. If yours is so dead that you have to short across it to make the radio work, then you should think about replacing it with either a watch battery or a resistor/cap combo. The set will perform better once the proper tube bias is in place.
