Last week I was asked to go to look at a radio that needs repair. The radio is Heli Admiral UKW 55. It is huge and heavy console with a phonograph. It looks very much like the "Plauen 56 UKW" that is listed in radiomuseum but doesn't have the reel-to-reel player. The radio was bought in 1955 according to the owner.
I downloaded a schematic for an Admiral 8/11 from radiomuseum because that was the only Admiral schematic that was available. Does anyone know if the UKW 55 uses the 8/11 chassis? It looked very much the same than in the 56 UKW.
The problem is that the audio is weak. The volume control has to be in the full position and radio station selectivity is not good. I measured the voltages at the filter capacitors and they were 287 and 227 volts after the radio had been on for a while. Do these voltages look correct? I don't know what they are supposed to be because the schematic doesn't say it. The radio also hums slightly. The radio has never been serviced before. The only thing that I can think of that is wrong are the paper capacitors. My plan is to remove the chassis and take it to home and change all of the paper capacitors. I will also change the electrolytic filter caps. It is not practical to remove the power supply section and other components so I'll need to test the radio where it is. I do realize that the problem may also be a weak tube or tubes but I think that the paper capacitors need changing anyway.
If you can give me any advice and tips of how to repair this radio I'd be very grateful.
