Mysteriously Mute Maestro

[Joe]

I've just been looking on e-Bay (and wishing I hadn't after seeing the prices!) and there's a photo of a boxed one that's nearly as 'bad' as mine.

I dare say I'll come across another to at least test it with as radios seem to keep coming my way and I've got a definite preference for AC/DC ones.

Thanks
- Joe
