Is there any information on the net, ie schematics, for the 1941 Zenith 7A04 Chassis. Thanks

My research indicates to use Rider Zenith page 12-1. This is for chassis 7A02 and 7A04 apparently. Chassis 7A04 is mentioned briefly as consuming 10 more watts which may be for those models with a phonograph. Quite a few models used this same chassis. Rubber insulation can be a real headache from radios of this period.

For some reason I am thinking the Schematic I need is on page 12-20. I dont see my model (7-s-582) or similar models listed on that sheet. I assume you are saying that this schematic is similar just not as much power.

Didn't see anything definitive on 7-S-582.

Zenith page 12-28 shows your model for the phonograph connections only and was assuming the addition 10 watts was for the phonograph's motor. Suggests to me the 7A02 is non-phono and 7A04 is phono. Wish I could have been more help. Good luck!
