Replacement dial string for a Nordemende Galaxy Mesa 7000
My mother brought this radio with her from Germany in 1971 I think. It's sat in my folk's basement for many years and I'm not sure what all is wrong. I know it needs new fuses and a powercord replaced but I've noticed the 2nd knob down from the top is very hard to turn. I do know it needs the string replaced and I have no idea where to get some. Nothing looks black or burned in the electronics and I've been spraying it with electrical cleaner. It has several years of gunk and dust so I'm taking my time hosing it down with the cleaner. I just downloaded and saved the schematics. Now I just need to find some string because it's either broken or getting ready to. Can someone help me find replacement string? Thanks for your time!
