Do you have an antenna connected to the set? It needs at least 25 feet of wire; longer is better.

The even stranger thing is that the " 24 " second detector plate has over the double ( 230 v. ) what it should be!! The other plates are only sl. high.

Did you check all resistor values? What is your line voltage?
