My Allied-branded Pioneer SX-990 has recently begun giving random problems with the FM tuner. Every once in a while the audio crackles in and out. It doesn't do this on any other function. I have messed with all the controls and switches, and they were recently cleaned. The signal meter does not drop out when this happens. The stereo light is burned out, so no idea what that would be doing.
Does this sound like a familiar symptom to anyone? I haven't brought it home from work yet to poke around at. Its all original inside, so probably overdue for some service by now anyway. I'm hoping for a cracked solder joint or something along those lines, but if anyone knows of specific potential problem areas I'd love to hear about it. When it comes home it will get a cleaning, new lamps, and a complete checkup at least. The volume control was replaced years ago with the wrong value, and the original knob is long gone so I'd also like to try and sort that out while its on the bench.
Thanks
