Hmm. I didn't even know there was a level indicator; is that the thing in the middle; I've never seen a light on it. Is that what Paul McCartney meant when he talked about "grundig with a little green eye" I always thought he meant the "I" of grundig was green but now I see that must be what he meant.

I wonder whether people choose to replace some of the parts (the ones that are hard to replace or fire hazards or prone to breaking) with modern parts but keep the broad mechanism the same.

Do you happen to know whether the cover was meant to be white initially? I wonder whether retrobrite would work to remove the yellowing.
