Grunow 835 question
#5

I have run into this problem before on an AC/DC radio. In my case it was a 22,000 ohm resistor on the 12SA7 converter tube, it would not oscillate on the lower frequency end of the broadcast band. It may or may not be the problem on the Grunow but it's worth checking, even if it has a separate oscillator tube.
Regards
Arran
