my grundig satellit 5000 radio sensitivity is poor
finally i find c501 15nf is shorted,cause the af126i transistor base bias is too low
change capacitor then work normal
i have a question ?
why this radio volume is on min position but the audio hiss noise is a little high?

Post linked to wrong model / audio hiss noise
Dear Mr. Chiang-ping
Your post ist obviously linked to a wrong model (Grundig Musikgeraet 2550 ID=26074 instead of Grundig Satellit Transistor 5000 ID=71126)
Please ask the Moderator to move this thread to the right model.
Concerning your question, I would suggest to have a look at the AF stages. I had a similar problem with a Grundig RTV900a. One of the audio channels had a disturbing hiss which could not be controlled by the volume. All Tensions in the circuitry were ok. After changing the AF pre-stage, the hiss had gone.
Kind regards
Marc
