I've got an Optronic (Sharp) SA-5905 and FM stations can't be locked in... The servo lock light blinks and the signal cuts in and out... Any ideas?

Basically, if it's old, adjust the detector coil. Coils drift.

If it doesn't use ceramic filters, that is there are interstage IF coils or transformers, make SURE you only adjust the detector coil. It takes too long to explain how to do a proper IF alignment on an FM reciever. If you can't identify the right coil don't do it.
