Hi Martin,
Thanks for your greetings.
I have checked out the excellent book by Jarman and Jarman and it looks like the beomaster 901. But if I am not wrong it was marked 801. Ther is also a matching casette deck Beocord 900 ( but again it might have been an 800 as I didnt have a chance to check out the model no on it).
It is sitting in an antiques store as a complete system with matching shelf speakers that look a lot like S22s.
So looks like I should buy it - it looks absolutely stunning! And when I have it will photograph and send to the forum.
Kind regards
Simon
