Sigh.......Ever heard of a Company called Quad? Believe it or not, but they have a service dept. and are able to supply parts for
Quad products such as the FM4 tuner. They even have a website and contact details. I'll leave you to figure out how to find it.
Hint: Google.
Failing that, if it isn't too much of an effort,and assuming you could find their website, maybe you could buy the battery from
Farnell Electronics - part number 863970.
