Thanks to this thread, I was able to clean up and improve a lowly SX 3400 Pioneer. The baby of the 1980 lineup. She's singing sweetly now. No locomotive rumble anymore.
However, my SX3700 (also acquired the same day as the 3400) which should have a far better tuner, WILL NOT lock onto anything in stereo. Mono, it'll do okay, tho the 5 lights for signal strength don't budge, or at least don't light up (local NPR station, which is usually maxing any signal meter, hits 2 out of 5).
The "stereo" light doesn't come on, even when in stereo (which I can only pick up the NPR station, not a single other one) and so I don't know if its burned out or what. On my old 7065, when the stereo bulb burned out, it wouldn't go into stereo mode. Odd, yeah, I know. Replaced bulb, stereo once more.
The 3400 is KILLING the 3700. I've cleaned it a couple times, but still no "stereo" light, tho it does light up "FM LOCK" on the NPR station.
Another cleaning, or something that needs a tech? Thanks, Warren, for your fine thread.
