Hellooooo, found these in my gran's house and in need of some help from the STW hive-mind. The amp is a Grundig RTV-320 and the speakers are also by Grundig.

I realise the sound isnt going to be great, but they are cool as ken and still work, however the amp has quite alot of interference in the controls.
So basically what im asking is 1. are they worth much? (not that im going to be selling) 2. how much approximately would it cost to get the amp/tuner serviced?? They're lovely looking components and have quite alot of sentimental value too.
Thanks for any help!!
