I am repairing a Grundig 4055W/3D-56 and the MW/LW/SW is working fine, but only the FM is not working. I have replaced the 10 uF elco in the FM detector, but I hear nothing than a little bit noise (with the volume at maximum level). I exchanged the EABC80 and ECC85 and doesn't matter.
When I use a small transistor FM radio to test the local oscillator of the Grundig radio and I tune this at 100.7MHz and I tune the Grundig 4055 to 90 MHz I don't hear nothing on the transistorradio. Even when I turn the dialknob from the beginning to the end of the Grundig, I don' t hear a signal on my transistorradio.
The voltage on pin1 (anode of first triode) is 145 V, the voltage on pin 6 (anode of second triode) is about 132 V.
Does somebody know if there is a technical explanation of the FM tuner of this radio? What could be the reason that the oscillator is not working.
I use the output of the FM tuner of my Telefunken Opus 7 radio and connect it to the first grid of the Ech81 tube of the 4055 radio. Now I have a good sound, so the mf amplifiers and FM detector works fine and the problem is in the FM tuner of the 4055.
