Hello, I am hoping to get a little information and advice concerning a project I have started. It is a Telefunken Operette 6 radio that was recently given to me. I am not an electrical engineer or technician, just a new hobbiest.
When I got the radio I plugged it in to see if it worked (I now know, wrong thing to do), it would receive fm signals but there was a loud humming in the background. Some research I’ve done tells me this is probably due to a faulty filter capacitor. I plan to replace all of the paper caps in the radio but am unsure about where the filter cap is located. The schematic is written in German which makes it very difficult for me to understand. I found a key for German electrical symbols on line but it is also written in German! I have included 2 attachments, one is the schematic and the other is a picture of what may be the filter cap or maybe a rectifier.
I read with interest a posting from a few years ago pertaining to the same radio but they did not identify the black AEG component, at least not to my understanding. Any help in locating the filter cap will be greatly appreciated.
