Don't usually post here as transistor sets are not my deal, but I have this model I bought in Germany in 1983 and it's giving me some problems. The only way it plays is with the volume control set at full and then the sound from the speaker is about half what you'd expect. Does anybody know where I might find servicing info on this set? I looked on RM.org but the schematic and board layout drawings there are too small to read. There is also no alignment info there. Not listed in Sam's Photofact index either. Can anybody help? Thanks

This site is running painfully slow today, be patient.

Download all documents. Some are super high-resolution.
Alignment instructions are pictorial. Lol


:) Greg.
oh... in France this radio was branded Radiola.

Thanks Greg. That is exactly what I wanted. I'm changing out caps one at a time to try to get the volume back up to where it belongs. It helps to have a clear print to work from.

By chance this very model arrived here in my abode as well. After spraying the wave switch it plays very well. It is so young that I would not expect any C to be faulty. At the back is a switch Radio / DIN, it switches the audio amplifier between radio and external source. Did you check the switch for correct position and/ or oxydation? Did you test, if the audio is loud and clear, if you inject an external signal here?
