Right - had a quick test tonight and it appears to be in full working order! In fact the sound quality was perhaps slightly better than the BM54 flat pin I have. I did notice on the tape mode the dolby symbol which I hadn't seen before?
However, the reason for testing it was because I thought I had an issue with the BM54 flat pin. I now doubt there is an issue but I'll expand on that in a dedicated thread.
Cheers for the input though
