    There is a lot of confusion regarding the model number of radios associated with the Rogers R-371 chassis. This chassis was used in the Rogers model numbers 403, 404, 903, 904. All I have is these two pictures. If someone knows the correct model number for these could they please clarify it here. Also if you have pics of the other two model numbers could you please post them here or send them to me at:

    Thanks in advance for any info.

    I found this one online. It definitely identifies the 904. I’m still looking for help to ID the other ones.

    This one, found online, was described as a 403.

    The bottom of the first attachment is mine. It was a mess when I got it. Someone had replaced the speaker with a newer model and tacked on the two transformers for it to the back. They also put a large power transformer there over the chassis tag. It had been electronically rewired to use an 80 rectifier tube and a 6G7s. The tuning and volume plates say Rogers.
    The attachment of your last post is also mine. It has also been electronically modified to use two small tubes in place of the 89Rs. I’ve attached photos of the backs of these two sets along with pages from a price guide for the 371 chassis I received from a friend in Canada. It shows a price list for the 403 and the 903 with the 903 station selector and volume control plates reading Majestic.

    I will post some better pictures when I get a chance!

    Hi! Robin,
    If that isn’t a typo in your post above, your 6G7S is a direct substitute for the 89RS. Thank you for the info you provided above. I cleaned it up and enhanced it. I put a copy on Skydrive for you as well as some Hi-res schematics. I have three of these radios. Two looked unmolested but when I removed the chassis from the first one I found a tube tucked underneath. The second one had the original tube sockets and, except for some poor repair work, looks correctly wired. I posted a few pictures here. I also put a larger file on Skydrive. Here is the link:

    Just left click on the link and wait for it to load. When it opens up, click on the orange icons to view and download pdf’s. Click on one picture to view and download pictures.
    The schematics have notations showing what type of wire to use. For example RC is for rubber covered wire.
    Hope this helps.
    Bob

    Additional info: See R-371 note pic below. The 6G7S tube was a production change. It is difficult to determine when the radio was built. So, a 6g7S could have been original equipment.
