But: 
http://www.tube-shop.com/uk/prod_industrial_detail.asp?
ProductID=332&ProcessType=20
says its in stock, in England. Sit down before you check the price and
shipping in dollars.

Though the price at the US location is a little better:

ProductID=332&ProcessType=20

http://www.ivaza.cz/cs/files/folders/tubes_data/entry116.aspx says its
no longer made.

I saw hints that Alpha has also used the tube so there might be a chance
they have spares.

There may be more to be found, but I just looked at the first 100 of
1620 google hits searching for 4CX1600B.
