Pioneer SX-34B tube AM-FM receiver
Posting this just to keep the embers alive in this NG. Plus, I love this
little old receiver! Unfortunately, the FM doesn't work, but this has only caused me to listen to AM for a while now, and it's revived my respect for that almost-forgotten medium. |

I'm sure you'll get the FM going eventually... but the person that invented those @&%&@## FM tuner modules should be drawn, quartered, and burned at the stake.. |

No, really, I have no clue as to where to start. There is no signal, the tuning dial doesn't deflect at all as I go across the scalle, and there is no background FM hiss. I mean, could it be as simple as a bad tube? I cleaned all the switches with Deoxit, that quieted them down, but didn't help the FM. |

That oscillator/mixer tube is very very critical in that module.. if it's the tiniest bit weak, the LO will fail to oscillate. As an experiment, choose a strong station in your area, then connect a decent wire antenna to one of the antenna connections, and a signal generator to the other. Tune the dial to the spot where the station should be, then tune your signal generator to ~10.7 MHz higher than the station frequency... if you hear anything, then that gives you that tube as a starting point. |
