First topic message reminder :

I found this little radio in a yard sale. As far as electronically it looks untouched! I recapped the electrolytics, but I get no audio. I jumpered another audio transformer and did get a low buzz,but no reception. Also it has a huge resistor looking part, is that a capacitor? It also has a domino looking part? The forum would not let me post a picture link.
Thanks,

That's great! Always like to hear about successful repairs.
The finish may just have to be sanded and repainted. No solvents to be safe, from attacking the plastic case.

On your picture link problem, when you have a picture just right click on the picture you see on your screen even if its on another web page. Then click on properties, then click and drag and then copy the properties info. It should end in jpg or bmp, or common graphics file extension.

then edit your post and click on the button that has a small picture above the comment area, it will show a small chain and a blank box that you can copy the properties link in. Then click on OK and it will show the link in your comments. Go down to the review button and click on it. It should show your picture. Then click on send and it will reappear in your post.

Thanks Cliff, tubes checked ok. When i changed out that molded mica she went to singing!
The audio out transformer was bad too. It works amazingly well for a four tuber!

Hope this helps
You may need to check the tubes.
And make sure the dial lamp works, if it is missing then it may be the problem as current flows though it from the rectifier filament.
