Hi! I'm pretty new here joining because I purchased a SR-3A on eBay for a song. It works great except for the FM tuner. The tuner won't tune any stations and the 7 segment displays look like they have some segments that are brighter than others. I opened it up and I don't see any cruddy solder joints or bulgy capacitors and in general, the phono section works rather nice. Does anyone here have any experience with restoring a Nak tuner? Thanks in advance!
