Problems with General Electric F70 (1937) 1 Can somebody help solving this problem? I have restaured this radio (superheterodyne, 7 tubes, 3 bands). It worked well initially and suddenly stopped working. The radio tunes to a - only a few- frequencies bu only a BRRR noise is heard on the loudspeaker. - All the tubes have been checked and seem ok. - Just in case I replaced the converter (6A8). No improvement - Surprisingly, Injecting a signal with a signal generator (RF/AF)(Heathkit RF1) at the antenna, the AF is clearly heard at the loudspeaker. Changing the RF in the generator the radio tunes well at all frequencies in the 3 bands and AF is clearly heard. - IF is 465 kHz. Injecting this frequency at the antenna, AF is heard at the loudspeaker AT ALL positions of the tuning condenser. I do not understand why the radio seems to work well with the signal genarator and not with the external stations. The reception here is strong. Thanks in advance for your help León Shanghai, PR China
