I'm restoring a Sekretär III 697/75GWU 3D radio. There wasn't a schematic for this model in RMorg but I used a schematic for model Sekretär III 697/62GWU which I believe to be close enough. There are no component values in the schematic and I need to know the value of one resistor. It is burned open and the markings are no longer visible. I think it is R11 in the schematic (in the lower left corner, antenna circuit). I have no idea how it got burned. There is no visible damage in the other components.
Also I removed the 50 + 100 uF electrolytic capacitor can but I forgot to look which one is the first and which one is the second filter. I'm guessing that the 100 uF is the first. Am I right?
The final question is about the half wave selenium rectifier. I measured its resistance with a digital ohm meter and I got 1.3 megaohms in the other direction and 1.6 megaohms in the other. I assume that it is bad?
All answers will be greatly appreciated.
