Had a bit of progress tonight: after bulb replace the stereo light works, yey!
But no life in the signal strength meter. If I measure voltage between the red and blue wires were they connect on the circuit board I get a tiny 0.17v when I have good FM and 0v when there's no signal. So there's a small voltage to the meter. But it's not moving at all. To little voltage or broken meter?
Im also still struggling with the tuning cap. I can get it working for an hour or so after lubrication of the shaft but the it slowly jams up after a while.
Maybe I have to try getting it out and apart for cleanup. But afraid I will mess it up. The cord, alignment and all that...
