  1 I have a bunch of photos of a "AUTOMATIC" radio to upload but don't know what model it is.
Help me to identify it please.
Here are some of the pics.

Your photos shows probably this model C60X. Only difference to me is the dial. The labelling of BC frequencies is reversed compared with your picture. The tube line-up is missing at the model page, this should be altered.

Hope this will help.

  3 Hello Bernhard !!

It's not the same. If you look at the rear picture and compare with the schematics you'll see that the layout of the components dont match.
For your appreciation, I attached a  picture with both layouts.
Note the I.F. transformers size and position, tubes and other elements.

My best wishes,



Carl Travis

Hello Meyer,

Can you post the tube complement?
