Probably a failing speaker

Try an external one, being wary of the live chassis of course.

Sometimes they're repairable. Have a look here too: https://www.vintage-radio.net/forum/...jockey+speaker

Thanks for the quick reply. I think i will try an external speaker first as you suggested nick.

There are loads of other things it could be, of course, but it always pays to try the simple things first
