Dear Forum members,

I have a Zenith 7A02 chassis for restauration here. I dowloaded the circuit diagram for this set, and it appears that there is an important difference between this diagram and the chassis i have here. The diagram mentions only two connection points A and G, but the rear ot the radio has a 5-pin connector for the antenna.

This antenna is a Zenith "Rotor Magnet Wave", as you can see on some of the uploaded pictures.

Can anyone provide me withe the correct circuit diagram please?

Thank you
