VR301 is the VCO adjustment. It's located near the tuning gang. This would
be the easiest thing to adjust that might correct the problem. First take
note of where it's set so that if the adjustment doesn't work, you can
return it to its prior state. Then turn it slightly one way or the other
and
see if your stereo signal light comes on for more stations. If not, go the
other direction. Without a frequency counter, you'll need to trial and
error
this adjustment.

It's highly likely this is the problem. This setting can drift to the point
where the decoder can fail to switch to stereo. I've seen the same issue in
other stereo receivers.
